在添加不同含量Y₂O₃纳米颗粒（质量浓度分别为0，5，10，20 g·L^-1）的电镀溶液中沉积Ni-W合金涂层，研究了Y₂O₃纳米颗粒的加入对涂层显微组织、微观形貌和电化学腐蚀性能的影响。结果表明：Y₂O₃纳米颗粒的添加减少了涂层表面结节状结构，细化了涂层晶粒，增大了微观应变；当Y₂O₃纳米颗粒的质量浓度在5~10 g·L^-1时，所得涂层的表面粗糙度小于未添加纳米颗粒涂层的，但当质量浓度增至20 g·L^-1时，表面粗糙度高于未添加纳米颗粒涂层的；Y₂O₃纳米颗粒的添加提高了涂层的耐电化学腐蚀性能，并且当Y₂O₃纳米颗粒的质量浓度为10 g·L^-1时，涂层的耐电化学腐蚀性能最优。

The Ni-W alloy coating was deposited in the electroplating solutions with different content (mass concentration of 0, 5, 10, 20 g·L^-1) of Y₂O₃ nanoparticles. The influence of Y₂O₃ nanoparticle addition on the microstructure, micromorphology and electrochemical corrosion properties of the coating was studied. The results show that the addition of Y₂O₃ nanoparticles reduced the surface nodular structures of the coatings, refined the grains, and increased the microscopic strains. When the mass fraction of Y₂O₃ nanoparticles was between 5-10 g·L^-1, the surface roughness of the coating was lower than that without nanoparticles; when the mass fraction of the nanoparticles increased to 20 g·L^-1, the surface roughness was larger than that without nanoparticles. The addition of Y₂O₃ nanoparticles improved the electrochemical corrosion resistance of the coating. When the mass fraction of the nanoparticles was 10 g·L^-1, the coating had the best electrochemical corrosion resistance.
