Passivation of Titanium Metal

[TrueDestined]

OMFG NO GLOVES"!!!

[joeylawn36111]

I reccomend smoothing the cut edges with a file - they're razor sharp....

[aterack833]

try iridum

[mrpin3appl3]

Woah, platinum? I Wonder how much copper that is...

[everysnakesdream22]

I say to myself, ok 11 more nurdrage videos then I am off the computer, but yet I keep on adding more! YOU ARE JUST TOO AWESOME TO ABANDON!

[instrkt]

Found your passivation of titanium metal very interesting, I want to coat titanium

electrodes (perhaps Ti foil) with platinum, any guidance will be much appreciated.

[BCQD4]

HEY where do you get your platinum and titanium strips???

[staszek300]

Hi. Could you tell me: If i want to make KClO3 I must have a steal cathode and titan anode. A titan anode must be covered a layer cobalt oxide or manganese oxide? Cheaper for me is of course covered titanium anode cobalt or manganese oxide to protected the titan to passivated. What voltage must be keep? 5 V will enough?

[angeloflove75]

fuck ill use that metal for war tanks .

[orangechicken210]

@angeloflove75 specifically war tanks? huh, I didn't know that there were any other types of tanks!

[angeloflove75]

@orangechicken210 well maybe there are but i said it like that cus thas how they call it,i think i saw that in discovery channell.

[orangechicken210]

@angeloflove75 Yes, because everything on T.V. is correct....

[MrWolverine777]

Hi I was wondering if you think that  titanium sheet could be bent in a circle?I also want to make anode but need a circular one thanks!

[Ubojica6661]

Where can I buy platinum, and how much it cost? I need it for the fuel cell to convert the hydrogen into electric power

[aquapulsefuel]

Your smart! I like you.your subjects are way off centre and it is the only place I feel comfortable.

[grandeoliba]

You can make Dye-sensitized solar cells with inexpensive dyes :-)

[discaras]

can you coat it with gold or platinum works better?

[durbina09]

will you do a video on electrolysis of water i just bought a milwaukee orp meter with a platinum tip electrode and needed some help on how to go about it... (water quality)

[panzuman]

hello i bought an mmo anode from ebay and it is a titanium mesh and i was wondering if it will get destryoyed where it gets cut and put into solution. will it passivate? also would 40 amps from a computer power supply be good for chlorate production?

[misaluvakatsa]

ive noticed that with all your videos you say to subscribe rate and comment but for some of the videos ive come across you cannot leave a comment...i just thought id tell you...

[adriiPortillo]

How about GOLD ?

Can gold be used to plate a titanium electrode and be used instead of platinum? im just curious, not that i think its better than just buying it.

[ZeroFossilFuel]

Excellent demonstration.

[BlackDogSociety]

You should use MMO coated Ti or Ni anodes and platinum cathodes for the electrolysis of water. The MMO coating aids in the formation of O2 while the platinum aids the formation of H2. Commercial electrolyzers use this method to improve production. The MMO coating is made of oxides of metals such as manganese, tungsten and ruthenium, according to what I've read...

[NurdRage]

oh electrolyzing water is just a demonstration. The video was about showing how titanium passivates if used as an anode.

i'll be doing electrolysis in a later video

[BlackDogSociety]

Good, maybe you can demonstrate how to make a MMO coating too...

[NurdRage]

sorry, ruthenium is too expensive

[yahoorif]

can zinc stripes be a good anode?

[vik95170]

It works as well with coper and zinc !

[nyarvin]

What people usually mean by passivation is something different from what this video shows, which is normally called anodizing. Passivation is where you, for instance, put stainless steel in a citric acid solution in order to remove iron-rich spots on its surface and improve its rust resistance. Or it can mean a process to reduce the catalytic activity of the surface, as in preparing aluminum tanks to hold hydrogen peroxide.

[NurdRage]

Passivation can be done by anodizing, but not all anodizing leads to a passive surface.

i'm demonstrating in this video the blocking of current due to an inert layer of titanium dioxide forming, passivation.

While it is anodizing, giving this a title of anodization would be more misleading because that's not the objective.

Kind of like drag racing, it's true that it's "combustion of gasoline" but that's not the objective, better title is "drag racing" or even "organ donor tryouts"

[nyarvin]

Ah, okay. Looking it up, I see that the usage I'd always encountered isn't the only one.

[Nighthawkinlight]

Very cool. I have about 150 strips of paper thin Ti sheets that I purchased at an auction last year. I'm very much looking forward to your upcoming videos.

By the way, I just uploaded my sub for science video. It should go public in a day or less.

[NurdRage]

Excellent! i look forward to your video!

[haxo909]

Hi Nurdrage, I am interested in purchasing a platinum coated titanium electrode like the one that you used in this video, do you know where the original buyer got it from? I have already searched ebay and found nothing. Thanks in advance.

[Electrosphere75]

Where would Titanium be in the reactivity series? below or above copper?

[Electrosphere75]

How much does your Titanium strips and the Platinum-Titanium electrode cost?

[NurdRage]

@electrosphere75

titanium was scrap off ebay. $45 for three large strips.

platinum electrode was a donation, but it costs the original buyer $150.

[Gmc42082]

this could be used as a chemical diode.

[DjB2Productions]

Everyone this is an announcement...

NurdRage is a woman, and nothing is wrong with that, so why do you have your voice ptiched down? Thats all I want to know.

[NurdRage]

Assertion without evidence is the worse form of science.

[Notyiffhunter]

@DjB2Productions Prove it.

[WrCmdSaul]

>DjB2Productions

Yeah i agree with Notyiffhunter, Prove it.

i take it you got pictures/video or a DNA sample? post it on youtube.

[ILikeWeatherGuy]

@DjB2Productions omg really? ;D

[xxMadBomberxx]

That's nice but I like the voice the way it is.

[panzuman]

this is very true i got these mixed up at one point and dissolved a titanium anode in a chloride solution this made me sad and thnx for doing this nurd rage!

[MajereRaist]

Interesting stuff :P

[killman369547]

this is completely off topic but what are your thouhts on the toyota recall

[thebrad15401]

Typical Toyotta

[goodfeller2]

thank you for posting again and another great vid

[shodanxx]

is this the same effect that pure aluminium exposed to air passivates by forming a layer of aluminium oxide ?

does titanium also passivate when exposed to air ?

can the thickness of the passivation layer be increased like with aluminium ?

[stroock6394]

can you please do a video with thermite?

[capnquack]

I'm pretty sure that while he could make it he wouldn't want to use it - that stuff can burn through concrete.

[stroock6394]

i know. thats why i want to see him do a video with it!

[arnold02000]

Anodizing, cool. Have you done experiments varying the voltage to create different colors? There is an artist who uses platinum as his canvas. He uses a brush connected to the cathode. Through varying the voltage, he can "paint" different colors on the titanium. He has also experimented with various electrolytes. I wish that worked on aluminum.

[20kilovolt]

This experiment looks like to behave as an diode.

Is it possible to rectify a (low frequency) AC source?

Thanks DR.Lithium your video's are very instructive 5*

[NurdRage]

@20kilovolt

i suppose for academic interests you could make the equivalent of a diode with this.

But as you've said, the equivalent reverse leakage, parasitic capacitance, forward voltage drop and resistance are all terrible. A diode hacked out of a radio performs better than this setup.

[waltrulz]

could you make a video about electroplating copper to aluminum?

[pcred562]

OOOHH... Platinum.

[NurdRage]

@spastb00n

long story, i'll cover it in another video.

Bottom line, titanium is clean, doesn't corrode, is physically stronger than other metals, and cheaper than pure platinum.

[NOBOX7]

i do agree with u on this but i hope im not anoing you with my question of plating copper with platinum

[Xonegod]

Another awesome vid, by NURDRAGE. Hard core Chem FTW~!!!

..X..

[nattsurfaren]

Guys you can make some really cool ingredients with electrochemistry. Especially all pyrotechnical people should give special attention to this.

[killer2611]

lol a small fraction of my body is made out of titanium xD

[UltimateChaostorm]

It was hard to me to keep up with this stuff.

[zoneanime]

nice that means you will be showing , plating of other elements over Ti,......ZA

[Sven2Perroy]

greetings fella nerds!

[lillance785]

i didn't understand a word he just said XD

[NurdRage]

@lillance785

sorry about that, This video has subtitles to help. turn those on to make it easier.

[NOBOX7]

hey friend ,, great vid , i have a question though, in my past experance i have found that resistance heating of electrodes made of metals other then copper can cause excesive heating with only 10 to 15 amps at 12 volts, plastic melts at the temps i have observed in open bath testing, so my question is why not plate copper electrodes ,, im shure u have a very good reason for the titanium , i just wanted to tell you about the problems i have noticed during many test

[NurdRage]

@NOBOX7

Copper corrodes very easily if used as an anode, disintegrating with prolonged use. The conditions around anodes are very harsh and only a few substances, titanium included, can withstand them.

Therefore a titanium substrate is preferable to a copper substrate.

[NOBOX7]

thanks for the info and just so im clear i was asking if it is possible to plate copper with platinum, i am aware of how fast copper corrodes in a cell but im intrested to no if i could possibly make my own platinum plated copper plates for an oxyhydro torch im building,,, you see ss steel gets very hot ,, up to 210 watts of heat is lost in just 6 inches at .02 ohms as a result of using stainless steel . but if you no a way to plate copper with platnuim it would be an amazing find for me ...

[NurdRage]

@nobox7

It can be done, but i from what i understand it's not a good idea.

i think a problem with platinum coating copper is that if you have even a tiny crack in the platinum it starts to corrode the copper in that crack. the corrosion spreads underneath the platinum layer and eventually dislodges the platinum. Titanium on the other hand just passivates itself and stops further corrosion.

Better option might be to fill a titanium tube with copper and then platinum plate that. less resistance

[NOBOX7]

intresting , i see what you mean, kinda the way paint or rust can be removed with electrolysis

[Camdor5]

5% sulpheric acid?, well thats interesting

[abdual3000]

finaly, a video

[jessiebm123]

yayayayaya your back nurdrage!!!!!!! we missed you

[jbohbot1]

yay!! finaly, a video!

[kickit246]

Cool, I am relearning my highschool chemistry through the art of flash backs lol.

[ryan50ryan]

how long did it take to cut all that titanium?

[hobomnky]

yaaaaaaaaaaaaaaaay electro chemistry! my favorite

ty nurdrage

[95Barqs1]

Yeah, good point.

[bruningga]

Thanks @NurdRage

[pat1huey]

Commercially pure grade 2 Ti is not too expensive, or at least not the quantities in this video. Just search it out on ebay.

[TheMonkeySmoker]

im ready!!

[Phibins]

coo

[antiswattt2]

i loved electrolysis right since my teacher blew up a little bag of H2O by mistake.. thought he could blow the gas out of the pipe and then light.. no.. went bang right at his hand :P

anyways nurdrage.. doesnt such titanium plates cost a bit?

[Hydroxybenzeen]

@antiswattt2

Dude H2O is normal water.

I think you mean hydrogen?

Ti can be quite expensive..

[antiswattt2]

i meant H2O as the gas... >_> ''HHO'' hho or h2o.. same shit.. if you know alot about chemistry you really should know that H2O gas is really powerful and just made from electrolysed water?

[Paradox3121]

@antiswattt2

I hope you're trolling, I really do.

[LionStrategic]

@Paradox3121

Maybe he means H2O2 (Hydrogen-Peroxide), but you cant just put some electrodes in water to make it. That just produces a mixture of Hydrogen Gas, and Oxygen Gas. (Which is still an explosive mixture)

[Hydroxybenzeen]

@antiswattt2

No dumbhead!!

Hydrogen gas is made by elektrolysis of H2O!!

Hydrogen is verry explosive with oxygen, forming water angain.

I think you don't know a lot about chemistry..

H2O is water, H2 (gas) is hydrogen,

Retarded easy basic chemistry XD

Total reaction:

2 H2O -----> 2 H2 + O2

For every 2 moles of water that is converted, 2 moles of hydrogen are formed and one mole of oxygen. For every mole of water to converted it takes 2 mole of electrons.

[Hydroxybenzeen]

@antiswattt2

H2O in gaseous form, is allso called steam...

[Chemateur]

@Hydroxybenzeen, you're absolutely correct, but I think antiswatt2 is talking about a stoichiometric mixture of hydrogen in oxygen in the balloon, which makes the reaction of hydrogen more explosive and makes the balloon experiment more impressive than pure hydrogen. A lot of people incorrectly label this mixture as H2O gas.

[antiswattt2]

well great idea! can you make a video where you boil some water into a balloon and somehow really strangely makes it go bang? :D cuz that would be extremely weird.. doesnt explain why you ELECTROLYSE water to get explosive gas

[HazMatLabz]

@antiswattt2 electricity breaks the bonds between certain compounds. as you know, compounds are held together with electrons.

[antiswattt2]

exactly. (:

[Hydroxybenzeen]

@antiswattt2

The explosive gas we are talking about is a mixture oxygen and hydrogen, mixed in stoichiometric ratio's (2:1, by volume). Steam will not do a thing. Yes ok you can blow up a balloon with steam until the pressure is big enought to make it pop. But that has nothing to do with the "explosive gas" .

In my preveous post you can see the equalation of the reaction of the electrolysis of (acidified) water.

[antiswattt2]

yap.. i tried hydrogen and can easily tell that wasnt hydrogen.. we also tried igniting pure hydrogen gas in a metal container.. pretty loud but that metal can would have been spread around everybodys dead bodys if it was filled with H2O gas..

[aCagedApe]

That was an interesting video. I wonder if he will demonstrate the use of palladium as an electrode.

[DidntKnowWhatToPut1]

Can I ask why you modify the pitich of your voice? if not you really do have a deep voice!

[tashi37]

cool

[godsend420]

☆☆☆☆☆

[simbathewildcat]

nice anode-cathode/passivation vid

[hhmm89]

I thought you edited your voice to sound like that. But anyway keep that mike it sounds really cool that way.

[MrMalavon]

Pretty sure he means the whistling.

[The0Burger0King]

Keep the voice you have. It makes you sound like a really awesome scientist! (Not that you aren't already an awesome scientist)

[themassau]

@The0Burger0King more a badass one :p

[xhotshot12]

comment

[iamtheman698]

What did you use for an electrolyte (sodium)?

[afdhalatifftan92]

Agreed with insAneTunA...

[95Barqs1]

Interesting. It probably would have been easier, and certainly safer, to cut the titanium with a dual saw. Just a suggestion.

[rhn94]

wat? .. so you dint edit ur voice on purpose ? .. i thout u did it fr security or smthin :P .. (dnt wrry .. the terrorists wnt kidnap u &try to make a thermo-nuclear bomb! :P )

[dickrodson]

Cool vids from your way. Don't get  a new mic, I think you voice sounds cool. It sounds like the voice from SAW. Creepy but very catchy. Keep up the great work.

[zARCADEz]

i thought his vioce was edited for some sort of legal reason

[vevenaneathna]

great vid

keep em commin :)

[insAneTunA]

@NurdRage

This is a great video, I have been reading about this, but one can never know enough. More general knowledge about these exotic materials would help a lot to make things clear for people like myself who are experimenting with devices that produce HHO.

Thanks for sharing and showing this 5*

Some others are experimenting with nickel200 as electrodes for electrolysis. Do you know anything about the properties from nickel200 in regards to the electrolysis process?

Greets, iT

[MapleFr3ak]

It's his real voice.

[Sheynan55]

thx NurdRage!

great video! cant wait for the next one to come!

[jpthecreaton]

While we're talking about elechtrochemistry, i was wondering if you knew anything about these aluminum/copper batteries with sodium hydroxide as an electrolyte. the general idea that i read about is for use in a ice fishing shed and they supposedly ran a tv and lights for about 3 months. what i could not find is would this battery be rechargeable? the metals should plate back out of solution, shouldn't they?

[solojam]

can you do experiments on tungsten, thanks

[Necrowitch]

hehe new toys.

[nebonit]

I dont know how, but you seem inline with what ever my year 12 course is doing, electrochemisty :)

[briackman]

coolio

[DjB2Productions]

I always wondered, is this your real voice, if not why do you have a voice thing?

[daniel05451]

Interesting video.

[sammyboy1234]

Cool
