| 摘 要： | 利用SEM分析了纯镍铸层,以及用直流和脉冲工艺所制备N i-ZrO2纳米复合电铸层的表面形貌,研究了直流条件下镀液中纳米颗粒悬浮量对纳米复合电铸层在干摩擦状态下耐磨性的影响,并对纳米复合电铸层磨损表面的形貌和磨损机理进行了探讨。结果表明:纳米复合电铸层的表面形貌不同于纯镍铸层;由于纳米颗粒的强化作用,使纳米复合电铸层表现出优良的耐磨性,并且磨损机理发生了变化;纳米复合电铸层的耐磨性取决于其中纳米颗粒的复合量。

| Abstract: | The SEM was used to analyze the surface morphology of Ni electroformings and the Ni-ZrO2 nano-composite electroformings prepared by DC electricity and pulse technique. The effects of nano-particle content in solutions on the wear resistance of the nano-composite electroformings prepared under dry friction conditions were studied. Furthermore, the worn surface of nano-composite electroformings and their abrasion mechanism were investigated. The study results show that the surface morphology of nanocomposite electroformings is different from that of Ni electroformings. Because of the strengthening effects of nano-particles, nano-composite electroformings exhibit excellent wear resistance, and changes in their abrasion mechanism take place. The wear resistance of nano-composite electroformings depends on the nano-particle content in them. |
