Electrochemical Characterization of Plasma-treated Titanium Alloys

Titanium and its alloys are used in various industries ranging from aerospace components to biomedical implants. Ti-6Al-4V (UNS R56400; Ti64) has been used as a structural biomaterial due to its excellent corrosion resistance, biocompatibility, high strength and low Young's modulus. A known issue with Ti64 is the release of harmful metal cations that negatively impact surrounding tissue and cause adverse health effects. Prior research on plasma treated Ti64 with boron additions in simulated sea water has shown improved corrosion resistance; however, little is known on the degradation of these alloys in biological media. In this study, Ti64 with low levels of boron additions were plasma treated and characterized using electrochemical methods.
