 Metallic biomaterials have been widely used for decades in medical devices such as hip replacements, knee replacements, cardiovascular implants, dental implants, and orthopedic implants. However, these materials can be susceptible to corrosion due to the harsh environment of the human body. Corrosion can lead to device failure or even cause adverse health effects if not properly controlled. This review paper examines the various types of metallic biomaterials and their corrosion behavior in the body. It also discusses the mechanisms behind corrosion and how it can be controlled.
