Abstract

The literature contains many results from in vitro friction and wear tests for simulating the behaviour of human joint prostheses. However, they are difficult to correlate, even when they are not contradictory. In friction tests, several friction-mechanisms occur when the Ti-6AI-4V titanium alloy rubs against the UHMWPE polyethylene. Corrosion effects which increase wear happen when the 316L stainless steel is used in Ringer's solution. Ion implantation surface treatments have been performed on these three materials. When the operating conditions were optimized, an important reduction of wear and corrosion was observed. The property improvements are due to structural modifications in a thin layer of the materials.

摘要

文献中有许多关于模拟人体关节假体行为的体外摩擦和磨损试验的结果。然而，即使这些结果不相互矛盾，它们也很难相互关联。在摩擦试验中，当Ti-6AI-4V钛合金与超高分子量聚乙烯（UHMWPE）摩擦时会出现几种摩擦机制。当在林格氏溶液中使用316L不锈钢时，会发生增加磨损的腐蚀效应。已经对这三种材料进行了离子注入表面处理。当操作条件得到优化时，磨损和腐蚀显著减少。性能的改善归因于材料薄层中的结构改性。
