    摘要:

    利用脈沖換向電刷鍍方法制得了Ni/n—SiO2復(fù)合鍍層,并對鍍層進(jìn)行了表面形貌觀察和分析,測試了鍍層的摩擦學(xué)性能,與直流工藝條件下的快鎳鍍層和Ni/n—SiO2復(fù)合鍍層相比,采用脈沖換向電刷鍍工藝得到的Ni/n—SiO2復(fù)合鍍層,由于脈沖換向電流的細(xì)晶強(qiáng)化作用和納米顆粒的彌散強(qiáng)化作用,鍍層致密、晶粒團(tuán)尺寸細(xì)小、硬度高、摩擦系數(shù)低,因此耐磨性能更好。

    Abstract:

    Ni/n-SiO2 compositional coatings were electrodeposited by brush-plating with pulse-reverse current. Morphology, hardness, and tribological properties of the coatings were investigated and compared with those of Ni and composite coatings electrodeposited by brush-plating with direct current. The test results obtained indicate that Ni/n-SiO2 composite coatings electrodeposited by brush-plating with pulse-reverse current, because of the pulse-reverse current and the nano powders, possesses the fine crystal grains, high hardness and low friction coefficient, so it is a better wear-resistant coatings.
