Multi-layered functionally graded (FG) structure Ni-W/Er₂O₃ nanocomposite films were prepared by continuously changing the deposition parameters, in which the Er₂O₃ and W contents varied with thickness. The microstructure and chemical composition of the electrodeposited Ni-W/Er₂O₃ films were determined by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). The anti-corrosion and wear properties of the electrodeposition films were investigated by electrochemical measurement and ball-on-disk friction test. The microhardness distribution of the cross section of nanocomposites was measured by nanoindentation. The results showed that with decreasing agitation rate or increasing average current density, the contents of Er₂O₃ nanoparticles and tungsten were distributed in a gradient along the thickness, and the contents on the surface were larger. By comparison, FG Ni-W/Er₂O₃ films had better anti-corrosion and wear properties than the uniform Ni-W/Er₂O₃ films. Atomic force microscopy (AFM) and profilometry measurements indicated that Er₂O₃ nanoparticles had an effect on the surface roughness.

通过连续改变沉积参数制备多层功能梯度（FG）结构的Ni-W / Er ₂ O ₃纳米复合膜，其中Er ₂ O ₃和W的含量随厚度而变化。电沉积Ni-W / Er ₂ O ₃的微观结构和化学组成通过扫描电子显微镜（SEM）和能量色散X射线光谱（EDS）确定薄膜。通过电化学测量和圆盘摩擦试验研究了电沉积膜的抗腐蚀和磨损性能。通过纳米压痕测量纳米复合材料的横截面的显微硬度分布。结果表明，随着搅拌速率的降低或平均电流密度的增加，Er ₂ O ₃纳米颗粒和钨的含量沿厚度方向呈梯度分布，表面含量较大。相比之下，FG Ni-W / Er ₂ O ₃膜具有比均匀的Ni-W / Er ₂ O更好的抗腐蚀和磨损性能₃部电影。原子力显微镜（AFM）和轮廓测定法测量表明，Er ₂ O ₃纳米颗粒对表面粗糙度有影响。
