研究了离子束混合对一些金属摩擦性能的作用，发现经离子束混合处理后表面耐磨性能比未处理的提高４～１５倍。利用Ｘ射线衍射分析发现处理后的表面化学组成及微观结构都发生了变化，这正是耐磨性能提高的关键因素之一。本文介绍对试样Ｘ射线衍射分析的研究情况。
The effect of ion beam mixing on the tribological properties of some metals was studied. It was found that the wear resistance of the surface increased by 4 ~ 15 times than that of untreated by ion beam mixing. X-ray diffraction analysis showed that the chemical composition and microstructure of the treated surface were changed, which is one of the key factors to improve the wear resistance. This article describes the X-ray diffraction analysis of the sample research.
