Fretting corrosion comparison between 316L SS and CoCrMo alloys. Effect of Ti content on cast alloys CoCrMo

Résumé

160,000 total hip prostheses are implanted each year, in France (250,000 in USA). One in every 30 Americans has a hip prosthesis. Fretting corrosion, friction under small displacements (Tribocorrosion), has been identified as one of the worst mechanism of degradations concerning metallic implants [1]. Three metallic alloys principally are used for orthopedic implants: Ti-6Al-4V, CoCrMo and 316L. It is well known that Ti-6Al-4V alloy does suffer from fretting corrosion degradations. As a consequence and it is not used for femoral head, for example. In order to study the typical damages of CoCrMo and 316L by fretting corrosion, specific investigations were carried out on a unique device for controlling mechanical and electrochemical parameters. This work aims at investigating differences of fretting corrosion resistance between both alloys.
