Corrosion-wear and iron-release are common problems that influence the biocompatibility of the materials of hip joint prosthesis. The solution to this main challenge remains is to control the following two aspects—the amount of materials shed from wearing counterparts, and the friction and lubrication between moving components, i.e. femoral head and cup. In this study, a plasma case hardened micro-geometrical patterning was created on CoCrMo surfaces with possibility of usage for long-term MoP prosthesis bearing surfaces. This surface engineered surface showed improved performance of friction property compared to untreated surface, especially in the start-and–stop mixed lubricated regime. The wear rate of the fragile patterning was increased by three to five orders of magnitude by the sequential treatment of case hardening.
