    Abstract
    In most cases, the microstructure of implants is stable and changeless after implanted into the body. However, the metallic joint replacements would be worn during patients' movements. Their subsurface microstructures were deformed and changed. That may affect the corrosion resistance of the joint. Due to the complex surface situation on the worn joints, it was difficult to distinguish and evaluate the influence of the subsurface microstructure from surface roughness, wear debris, etc. In this study, a CoCrMo alloy used for artificial joints was treated by high-energy shot peening...
