在生物摩擦腐蚀过程中，金属人工关节释放出的碎片和离子对患者的健康构成了严重威胁。通过研究CoCrMo合金在体外的亚表面组织转变，揭示了该合金的生命周期。结果表明，合金表层由粗大的颗粒转变为纳米颗粒，纳米颗粒从表面剥离，并被摩擦膜阻挡。摩擦膜中团聚的合金纳米颗粒从合金表面去除后转化为碎屑。大部分被撕裂的纳米粒子由于具有较高的化学活性而被腐蚀并释放到溶液中。
The release of debris and ions from metallic artificial joints during bio-tribocorrosion posed a severe threat to patient health. In this work, the lifecycle of a CoCrMo alloy was presented by investigating the subsurface microstructure transformationin-vitro. The results showed that the originally coarse grains changed to nano-grains (NGs) on the top region of the alloy, and nanoparticles (NPs) were torn off the surface, which were then blocked by the tribo-film. The agglomerated alloy NPs contained in the tribo-film transformed into debris after being removed from the alloy surface. The majority of the torn-off NPs were corroded and released ions into solution due to their high chemical activities.
