 This systematic literature review examined the tribological performance of four different coatings. Diamond-like carbon, DLC, graphite-like carbon, or GLC, titanium nitride, tin, and tantalum, TA. The study found that TA had the lowest wear rate among the coatings tested, followed by DLC, GLC, and tin. Additionally, TA had the highest hardness and the highest elastic modulus, suggesting that it would be the most suitable coating for joint implant applications. Further testing is required to determine whether or not these results can be applied to real-world situations. This article was authored by He A Ching, Dipongka Choudhury, M.D. Jolkanine, and others.
