采用复合电沉积工艺于镀液中添加适量纳米微粒并辅助超声振动搅拌,制得镍基纳米复合材料。研究了该纳米复合材料的微观结构、结晶,并探讨了受稀土添加浓度的影响程度。结果表明:添加适量稀土制备的纳米复合材料表面平整性和结构致密性均较不加稀土条件下有所改善,且显微硬度和抗高温氧化性亦不同程度提高;随稀土添加浓度增大,纳米复合材料的形貌结构呈现变差趋向,显微硬度和抗高温氧化性均对应有所降低,而结晶取向未明显改变。 The composite electrodeposition process was used to add proper amount of nano-particles to the plating solution and assisted the ultrasonic vibration agitation to obtain the nickel-based nano-composite. The microstructure and crystallization of the nanocomposites were studied, and the degree of influence by the added concentration of rare earths was also discussed. The results show that the surface smoothness and the structural compactness of nanocomposites prepared by adding appropriate amount of rare earth are better than those without rare earths, and the microhardness and high temperature oxidation resistance also increase to some extent. With the increase of rare earth concentration, The morphology of nanocomposites showed a trend of deterioration, the microhardness and high temperature oxidation resistance decreased correspondingly, while the crystal orientation did not change significantly.
