Abstract
Ti alloys are well known for their biocompatibility and high specific strength. In the present work, the electrochemical behaviour of Ti–13Ta–29Nb–4.6Zr alloy having β structure in Hank’s solution containing various joint lubricants has been studied. The results show that Ti–13Ta–29Nb–4.6Zr alloy is a potential biomaterial for joint applications. The electrochemical behaviour of Ti–13Ta–29Nb–4.6Zr alloy is not influenced significantly by the nature of lubrication. The highest corrosion rate of investigated alloy is around 1.2 mm/year in Hyaluronic Acid containing Hank’s solution. The growth of passive layer is the slowest and the passive layer is the most porous in Hank’s solution containing hyaluronic acid.
