摘要(Abstract)：
针对Zn-Ni镀层耐磨性不足的问题，采用脉冲电沉积技术制备Zn-Ni-PTFE复合镀层，系统探究占空比、平均电流密度对Zn-Ni-PTFE复合镀层组织结构、PTFE复合量以及力学与摩擦学性能的影响。结果表明，占空比降低可提高PTFE复合量，当占空比为12.5%、电流密度为1 A/dm~2条件下制备的复合镀层的PTFE复合量最高达到28.47%(体积分数),水接触角达到了最高的139.6°;在占空比为12.5%、电流密度为2 A/dm~2条件下制备的复合镀层磨损率最低为3.2×10~(-8) mm~3/(N·m),其摩擦系数在摩擦过程中稳定维持在0.11。高电流密度(>4 A/dm~2)导致PTFE复合量骤减，镀层裂纹增多，润滑功能失效。在摩擦过程中镀层以磨粒磨损和疲劳磨损为主，PTFE补充机制可延缓摩擦系数上升，实现长效润滑。
