Tribocorrosion behavior of beta titanium biomedical alloys in phosphate buffer saline solution

摘要

The tribo-electrochemical behavior of different beta titanium alloys for biomedical applications sintered by powder metallurgy has been investigated. Different mechanical, electrochemical and optical techniques were used to study the influence of the chemical composition, Sn content, and the electrochemical conditions on the tribocorrosion behavior of those alloys Ti30NbxSn alloys (where "x" is the weight percentage of Sn content, 2% and 4%).
