發(fā)布時間:2023-10-26 20:09
本文研究了軸向柱塞泵滑靴副表面MoS2涂層的摩擦學性能。首先,利用等離子噴涂技術在滑靴副材料表面制備MoS2涂層。其次,采用環(huán)塊摩擦磨損實驗機考察材料在不同工況條件下的摩擦學性能。最后,基于能譜儀和掃描電子顯微分析以及試件磨損表面X射線衍射分析,探討了滑靴副表面MoS2涂層的摩擦機理。研究結果表明,當外部載荷為800 N時,含MoS2涂層的銅基體材料表面摩擦系數降低0.05;在MoS2涂層下的ZY331608試件具有優(yōu)異的抗摩擦磨損性能,其磨損率減少16.4%;銅基體材料表面形成MoS2潤滑膜的過程分為四個階段:初始摩擦階段、MoS2在摩擦表面的粘附階段、MoS2在滑動表面的覆蓋階段以及MoS2潤滑膜的形成階段;銅基體材料表面Mo S2涂層的主要磨損機制是粘著磨損、磨粒磨損和氧化磨損。
