对多晶铜表面电沉积Ni/Cu多层膜进行了滑动磨损和硬度测试。多层膜的总厚度为5 μm，单层厚度为5 ~ 100 nm。用纳米压痕测试仪测量的多层膜的硬度被发现是依赖于层的厚度。层厚为20 nm的多层膜显示出最高的值。结果发现，所有测试的多层膜的耐磨性高于电沉积镍涂层。结果还表明，多层膜的比磨损率随层厚的减小而减小，但在20 nm层厚时硬度最高。扫描离子显微镜观察表明，即使在滑动磨损后，亚表面区域仍保持镍和铜的层状结构。由于在蜗杆表面附近形成了严重塑性变形过程所特有的细晶粒，因此多层具有足够的塑性以适应来自滑动磨损的变形。
Sliding wear and hardness tests in Ni/Cu multilayers electrodeposited on polycrystalline copper substrate were carried out. The multilayers had a total thickness of 5 μm and an individual layer thickness from 5 to 100 nm. Hardness of the multilayers measured with a nanoindentation tester was found to be dependent on layer thickness. The multilayer with the layer thickness of 20 nm showed the highest value among them. It was found that the wear resistances of all the multilayers tested were higher than that of an electrodeposited nickel coating. It was also revealed that the specific wear rate of multilayers decreased with decreasing the layer thickness although the highest hardness was attained at the 20 nm layer thickness. Scanning ion microscope observation showed that the subsurface area kept the layered structure of nickel and copper even after sliding wear. The multilayer had plasticity sufficient to accommodate deformation coming from the sliding wear, because fine grains peculiar to severe plastic deformation process were formed near the worm surface.
