Abstract

Abstract This study was to determine to what extent a cryogenic surface treatment technique could improve the wear resistance of a Co-Cr-Mo hip implant material. Dry and cryogenic treatments were used to create different surface and sub-surface conditions. The Co-Cr-Mo samples were wear-tested using a pin-on-disk tester in a simulated implant environment. A change in the wear response was found as a function of the material surface properties. Correlation between the treatment conditions and wear volume loss was discussed. Sample from cryogenic treatment was found to be most promising with lower wear volume due to microstructure refinement, compressive residual stresses and preferred hcp phase; moreover, the preferred hcp phase revealed to be the most influencing property in enhancing the wear resistance.

低温表面处理提高Co-Cr-Mo髋关节植入物的耐磨性以改善其功能性能：一个案例研究

摘要本研究旨在确定低温表面处理技术能在多大程度上提高Co-Cr-Mo髋关节植入材料的耐磨性。使用干燥和低温处理来创造不同的表面和亚表面条件。Co-Cr-Mo样品在模拟的种植环境中使用针盘式测试器进行磨损测试。磨损响应的变化是材料表面特性的函数。讨论了处理条件与磨损体积损失的关系。低温处理的样品由于组织细化、压缩残余应力和首选hcp相而具有较低的磨损体积;优选的HCP相对提高材料的耐磨性影响最大。
