In vitro simulation of fretting-corrosion in hip implant modular junctions: The influence of pH

CoCrMo and Ti6Al4V are the most commonly used materials in total hip arthroplasties due to their combination of preferential attributes such as high strength, high resistance to corrosion, biocompatibility and high capacity to integrate with bone and other tissues [1,2]. Various physiological conditions present an aggressive chemical and mechanical environment to the implant [1,3 –5]. This leads to degradation of the implant material, and under extreme conditions, subsequent implant failure [1,3–5].
