用氮离子注入Ti-6Al-4V与超高分子量聚乙烯进行了联合试验，评价了不同条件下的磨损行为。结果表明，离子注入对聚合物的磨损率没有影响。另一方面，这种处理大大减少了金属的磨损。研究还发现，离子注入能很好地防止PMMA对金属表面的第三体磨损，而在接头中引入C.P.钛颗粒则会引发巨大的磨损。虽然离子注入改善了钛合金与超高分子量聚乙烯的摩擦磨损，但离子注入层的耐久性有待进一步研究。
Nitrogen-ion-implanted Ti-6A1-4V against UHMW polyethylene was tested on a joint simulator to evaluate the wear behavior under different conditions. It was concluded that the polymer wear rate was not affected by ion implantation. The metallic wear, on the other hand, was substantially reduced by this treatment. It was also found that ion implantation resulted in good protection of the metal surface against third-body wear by PMMA, while the introduction of C.P. titanium particles in the joint initiated tremendous wear. Although ion implantation improved the wear of titanium alloy against UHMW polyethylene, the durability of the implanted layer needs further study.
