This research work describes the impact of the surface mechanical attrition treatment (SMAT) on the microstructure of cobalt–chromium–molybdenum (CoCrMo), a biomedical alloy commonly used for orthopedic applications. This surface treatment induces crystalline phases transformations characterized by X‐ray diffraction (XRD) and selected area electron diffraction (SAED). The corresponding structural changes are observed from cross‐section images obtained by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results show that the SMAT process induces the martensitic transformation of the CoCrMo alloy (from γ‐fcc phase to ε‐hcp phase) related to an important grain refinement due to twinning and sliding.

表面机械磨损处理对钴铬钼生物医用合金显微组织的影响[J].

这项研究工作描述了表面机械磨损处理 (SMAT) 对钴铬钼 (CoCrMo) 微观结构的影响,钴铬钼是一种常用于骨科应用的生物医学合金。这种表面处理会引起结晶相转变,其特征是 X 射线衍射 (XRD) 和选区电子衍射 (SAED)。从通过扫描电子显微镜(SEM)和透射电子显微镜(TEM)获得的横截面图像观察到相应的结构变化。结果表明,SMAT 过程引起 CoCrMo 合金的马氏体转变(从 γ-fcc 相到 ε-hcp 相),这与由于孪晶和滑动导致的重要晶粒细化有关。
