The Tribological Characteristics of the Electroless Composite Coating of (Ni-P)-TiO_2 Nanometer Particles

通过对化学镀 Ni- P合金、化学复合镀 ( Ni- P) -微米 Si C微粒复合镀层和化学复合镀 ( Ni- P) -纳米 Ti O2 微粒复合镀层研究与比较 ,探讨了化学复合镀 ( Ni- P) -纳米 Ti O2 微粒复合镀层的摩擦学特性。研究发现化学复合镀 ( Ni- P) -纳米 Ti O2 微粒复合镀层由于其良好的组织与性能 ,滑动磨损过程中具有低的摩擦系数和高的耐磨性。

By comparing the electroless composite coating of (Ni P) (TiO 2 nanometer particles) with the electroless composite coating of (Ni P) (SiC micrometer particles) and electroless plating Ni P alloy coating, the tribological characteristic of the electroless composite coating of (Ni P) (TiO 2 nanometer particles) has been discussed in this paper. The result shows that because of the good structure and mechanic properties, the electroless composite coating of Ni P (TiO 2 nanometer particles) has good wear resistance and low friction coefficient in the sliding friction, especially in high load condition.
