轴向柱塞泵滑靴副表面MoS 2 涂层的摩擦学性能(英文)
发布时间:2023-10-26 20:09
本文研究了轴向柱塞泵滑靴副表面MoS2涂层的摩擦学性能。首先,利用等离子喷涂技术在滑靴副材料表面制备MoS2涂层。其次,采用环块摩擦磨损实验机考察材料在不同工况条件下的摩擦学性能。最后,基于能谱仪和扫描电子显微分析以及试件磨损表面X射线衍射分析,探讨了滑靴副表面MoS2涂层的摩擦机理。研究结果表明,当外部载荷为800 N时,含MoS2涂层的铜基体材料表面摩擦系数降低0.05;在MoS2涂层下的ZY331608试件具有优异的抗摩擦磨损性能,其磨损率减少16.4%;铜基体材料表面形成MoS2润滑膜的过程分为四个阶段:初始摩擦阶段、MoS2在摩擦表面的粘附阶段、MoS2在滑动表面的覆盖阶段以及MoS2润滑膜的形成阶段;铜基体材料表面Mo S2涂层的主要磨损机制是粘着磨损、磨粒磨损和氧化磨损。
