摘　　要：在化学沉积Ni-P镀层的工艺基础上,通过改变镀液中添加的表面活性剂和纳米PTFE的含量,制备了Ni-P-PTFE复合镀层,并研究了镀液中表面活性剂和纳米PTFE的含量对复合镀层的力学和摩擦学性能的影响。研究结果表明:当镀液中的表面活性剂和纳米PTFE添加量均为6 g/L时,所得的Ni-P-PTFE复合镀层PTFE含量较高,具有优良的力学和摩擦学性能,其磨损机制主要为粘着磨损,并伴随轻微的磨粒磨损。Ni-P-PTFE composite coating was prepared by content changing of active agent and nano-PTFE on the base of Ni-P coating technology.The effects of active agent and nano-PTFE content on mechanical and tribological properties of composite coating were investigated.The results indicate that Ni-P-PTFE composite coating prepared with active agent of 6 g/L and nano-PTFE of 6 g/L has beneficial mechanical and tribological properties,and wear mechanism of composites are abrasive wear and slight grain wear.
