Abstract: BACKGROUND: Surface treatment technology has been widely used in biomedical field, which can effectively improve the friction and wear properties of artificial joints materials. OBJECTIVE: Taking the friction and wear performance of artificial joints as the research object, to summarize the application and development of surface texture technology and surface coating technology in the friction and wear performance of artificial joints in recent years. METHODS: Studies on the surface treatment technology, friction and wear performance of artificial joints were searched by computer on ScienceDirect, SpringerLink, EBSCO, Web of Science and other databases. The retrieval words were “artificial joints, friction, wear, surface treatment/surface modification”, and the retrieval time was from March 2000 to June 2020. RESULTS AND CONCLUSION: Surface treatment technology is mainly divided into surface texture technology and surface coating technology. Surface texture technology will affect the microstructure of artificial joints, so as to optimize the performance of artificial joints. However, not all texture structures can improve the friction and wear performance of artificial joints. When the initial roughness value of the surface texture structure is too large, it will inhibit the hydrodynamic effect of the texture structure and weaken the friction and lubrication performance. Surface coating technology will affect the surface performance of artificial joints, thus increasing the service life of artificial joints.
