聚醚醚酮及其改性的人工关节材料的摩擦磨损性能研究进展

The research progress offriction and wear properties of polyetheretherketone and its modified materials for artificial joints

聚醚醚酮(Polyetheretherketone,PEEK)优异的耐磨损性能为研发新一代高寿命人工关节提供了新希望。分别综述了采用常规摩擦学方法对纯PEEK、碳纤维增强PEEK、颗粒填充PEEK、等离子改性PEEK等作为人工关节材料,和采用模拟试验机方法对PEEK在人工髋关节、人工膝关节等假体关节面发挥耐磨损性能的应用和研究进展,最后展望了PEEK及其改性的人工关节材料摩擦磨损性能研究的发展趋势。

Polyetheretherketone(PEEK)provides new hope for the development of the long lifetime artificial j oints due to its excellent friction and wear properties.The application and research progress for the friction and wear properties of PEEK,carbon fiber reinforced PEEK,particle-filled PEEK,plasma modified PEEK applied as artificial j oint material surface using conventional tribology method and on articular surface such as total hip, knee and artificial intervertebral disc prosthesis using simulators were summarized respectively.At last,the de-velopment trends were prospected.
