高性能陶瓷人工髋关节材料摩擦磨损研究发展

Advances in Friction and wear studies of High Performance ceramics for Hip Joint Prostheses

陶瓷已经在人工髋关节假体制作中获得一定的应用 ,并且有更大的潜力以待开发。对于陶瓷人工髋关节假体 ,其摩擦磨损性能是决定其寿命的最重要的性能之一 ,而体外的摩擦磨损测试对于确定其摩擦磨损性能有着重要意义。本文综述了国内外对于氧化铝、氧化锆、氮化硅和碳化硅四种陶瓷的摩擦磨损性能的研究结果 ,并且结合作者的工作对其进行评论。

Ceramics have been used to make hip joint prostheses for many years and they still have huge potentials to be developed.To ceramics hip joint prostheses,friction and wear properties are one of the most important factors determining their lives.Friction and wear tests in-vitro are very important to determine the friction and wear properties of ceramics materials.In this paper,the authors summarize the results in the friction and wear studies of alumina,zirconia,silicon nitride and silicon carbide ceramics and then give some comments.
