| 摘 要： | 利用脉冲换向电刷镀方法制得了Ni／n—SiO2复合镀层，并对镀层进行了表面形貌观察和分析，测试了镀层的摩擦学性能，与直流工艺条件下的快镍镀层和Ni／n—SiO2复合镀层相比，采用脉冲换向电刷镀工艺得到的Ni／n—SiO2复合镀层，由于脉冲换向电流的细晶强化作用和纳米颗粒的弥散强化作用，镀层致密、晶粒团尺寸细小、硬度高、摩擦系数低，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. |

| Keywords: | direct current(DC) pulse-reverse current(RC) brush-plating nano composite coatings |
