Influence of protein adsorption on tribocorrosion behaviour of CoCrMo biomedical-grade alloys

CoCrMo alloys have been widely used in metal-on-metal hip replacements. They exhibit excellent long-term survival rates; however, recently, high failure rates associated with adverse local tissue reactions have been observed. CoCrMo alloys generally work extremely well; however, sometimes their wear rate is high. This work investigated protein adsorption effects on the tribocorrosion behaviour of CoCrMo biomedical-grade alloys under different...
