摘要： Bodies made of titanium or its alloys, having surfaces liable to wear, have their wear resistance improved by coating such surfaces with a layer of a metal such as tin or aluminum which has been bombarded with ions of a light species such as nitrogen, carbon, boron, or neon so as to cause the metal to migrate into the titanium or titanium alloy. The modified surface has improved wear resistance and reduced coefficient of friction.

摘要： The present invention provides methods for modifying surfaces made from metal alloy and/or UHMWPE, preferably surfaces which are frictionally engaged, e.g., in an orthopaedic implant. The methods of the present invention reduce the coefficient of friction of the metal alloy component, reduce the shearing of fibrils from the UHMWPE component, and reduce sub-surface fatigue in the UHMWPE component. The method involves solvent immersion of the UHMWPE component to remove short chains of polyethylene at or near the surface of the component, and to swell and toughen the subsurface of the component. The method also involves firmly coating the surface of the metal alloy component with an adherent layer of diamond-like carbon (“DLC”) by creating a metal-silicide interface at the surface of the metal alloy to permit firmer adhesion of DLC. Although the methods of the present invention are particularly useful in orthopaedic applications, the methods also can be used to treat similar components used in other applications.
摘要翻译： 本发明提供了用于修改由金属合金和/或UHMWPE制成的表面的方法，优选的是例如在矫形植入物中摩擦接合的表面。 本发明的方法降低了金属合金组分的摩擦系数，减少了UHMWPE组分中原纤维的剪切，并降低了UHMWPE组分的表面下疲劳。 该方法涉及UHMWPE组分的溶剂浸渍以除去组分表面处或附近的聚乙烯短链，并且膨胀并增韧组分的表面。 该方法还涉及通过在金属合金的表面产生金属硅化物界面，用金刚石状碳的粘附层（“DLC”）来牢固地涂覆金属合金组分的表面，以允许更牢固地粘附DLC。 尽管本发明的方法在矫形应用中特别有用，但是该方法也可用于治疗其它应用中使用的类似组件。
