The friction and wear of artificial joints is still the most important problem in basic research.It is necessary for the future development of artificial joints to improve the tribological behavior by means of surface modification technology.From the perspective of lubrication,the research on the friction performance of prosthesis joint mainly focuses on the design of surface functionalized lubrication structure and the new bionic lubricants.In view of the functional lubrication structure,the surface texture design and the application of polymer brush were mainly introduced.The influence of surface texturing parameters on the performance of friction pairs under different motion conditions was analyzed,and the lubrication mechanism of surface texturing was expounded.The regulation of the wear resistance of friction system by different kinds of polymer brushes was summarized,and the water lubrication characteristics of polymer brushes at the friction interface were clarified.The effects of environmental media on the structure and properties of polymer brushes were proposed.In view of the joint lubricant,it was introduced that the traditional synovial fluid components were extended to polymer bionic lubricants.It was pointed out that the embedded design of micro/nanostructures and the combination of synergistic lubrication and lubricant structure bionics with functional bionics will be the important development direction in the future.
