Corrosion Residue Debris Left by Implant Materials to the Patient’s Body | Biomedgrid

In the field of biomaterial science, the corrosion of metallic implants in the body cannot be avoided so the selection of biocompatible and corrosion resistant materials is so important, whereas the corrosion can decrease the lifetime of implants. Human body represents a very aggressive corrosive environment to metallic implants. Although some pure or commonly known alloys as implants can be used in combination with the body when used alone, they can cause problems if used in places where material pair is used without observing the electrochemical potential difference between them. As a result, electrochemical corrosion will happen. A Battery formation due to electrochemical potential difference between materials and subsequent electron transfer increases the amount of debris that breaks from metal in the body environment. Debris formation and their effects on the human body are the initial reason for shortening the duration of implant leading to implant failure and of course revision operations.
