分别在单一超声和组合超声条件下制备了 Ni-Nd₂O₃ 纳米复合镀层,分析了镀层的微观形貌,测定了镀层中纳米 Nd₂O₃ 的含量,考察了纳米复合镀层的耐腐蚀性能。 结果表明:组合超声可以提高 Ni-Nd₂O₃ 纳米复合镀层中 Nd₂O₃ 的含量,在组合超声空化效应和协同效应的作用下,复合镀层的晶粒细化,组织致密,腐蚀速率降低,表现出优良的耐腐蚀性能。

The Ni-Nd₂O₃nanocomposite coatings were prepared by electrodeposition with single-ultrasound and combination ultrasound, respectively. The surface morphologies of nanocomposite coatings were analyzed and the Nd₂O₃content in nanocomposite coatings was measured. The corrosion resistance of Ni-Nd₂O₃nanocomposite coatings was studied. The results show that combination ultrasound could increase Nd₂O₃content in Ni-Nd₂O₃nanocomposite coatings. Under the synergy and cavitation effect of combination ultrasound, the nanocomposite coatings have refiner grains, more compact microstructure and exhibit excellent corrosion resistance, and show excellent corrosion resistance.
