中文摘要：
为了提高材料的表面性能,采用表面机械研磨处理和机械合金化相结合的方法,在纯铜表面形成一定厚度的沉积镍层。采用X射线衍射仪（XRD）和扫描电子显微镜（SEM）对试样的显微组织结构进行分析,试样的机械性能采用金相显微硬度测试仪进行测试。实验结果表明,纯铜表面经机械沉积镍处理后,表面平均晶粒尺寸达到了纳米量级;随处理时间的延长,表面硬度得到了改善。
英文摘要：
To improve the surface properties of materials,Ni alloy layer was produced on pure copper by a combination of surface mechanical attrition treatment and mechanical alloying.The microstructure of the samples fabricated by mechanical deposition was investigated by scanning electron microscopy and X-ray diffraction instruments.Mechanical properties of specimens were tested by micro-hardness tester.The experiment results indicated that nanostructured alloying layer was formed on pure copper by mechanical deposition.With the prolonging of treatment time,micro-hardness and corrosion resistance of specimens were greatly improved
