Hip replacement stems manufactured from Ti6Al4V titanium alloy were surface treated in one of four ways and tested for dissolution resistance in bovine serum. Those stems treated thermally were found to have significantly lower metal ion release compared with those receiving standard commercial treatments. The improved dissolution behaviour is associated with a change in the surface oxide structure from mixed titanium oxides to a more stable rutile structure.
由Ti6Al4V钛合金制造的髋关节置换柄采用四种方法之一进行表面处理，并在牛血清中测试其抗溶解性。结果发现，与接受标准商业处理的柄相比，经过热处理的柄的金属离子释放量显著更低。溶解行为的改善与表面氧化物结构从混合钛氧化物转变为更稳定的金红石结构有关。
