Surface/Environment Interactions of CoCrMo

Metal has been used in orthopaedic implants due to possessing excellent corrosion resistance and bio-compatibility. During recent years there has been serious concern using metal implants as release of metal ions from the implant can lead to genotoxicity and immunological effects with one of the principal factors that lead to this being the electrochemical reactions of the implant with salts proteins and other organic substances in the body. Continuous degradation also affects the lifetime of the implant; lifetime of the implant is a current priority due to the increased need for joint replacement in younger population.The focus of this research is to fully understand the surface/environment interactions that occur on CoCrMo alloys whilst in a protein-containing environment. Electrochemical techniques to measure corrosion rates and post –test assessment to assess mechanisms under a variety simulated body fluids have been used. X-Ray Photoelectron Spectroscopy (XPS) has been employed to analyse the surface chemistry of CoCrMo throughout the formation/dissolution of the organic/metallic tribo-film whilst In-Situ AFM has been utilised to monitor the build up of proteins in real time to determine how reactant films resulting from protein/surface interactions are formed. This study has shown that the presence of proteins has a substantial effect on the metal/oxide/electrolyte interface and this subsequently affects how the metal will behave in an implant environment
