摘　　要：研究了粉末热锻浮动油封密封环的材质、表面处理、显微组织对其耐磨性的影响。试验结果表明粉末热锻FeCuMoC材质浮动油封密封环的表面硬度大于HRC63,工作表面存在弥散微孔,具有贮油作用,有利于油膜形成,从而提高其耐磨性。The effects of material composition, working surface treatment and microstructure on wear resistance of powder hot-forging flow oil-seal ring were studied. The result of test indicates that the surface hardness of powder hot-forging Fe-Cu-Mo-C flow oil-seal ring is more than HRC 63 and there are dispersion tiny holes on working surface, which can store lubrication oil to form oil film and increase wear resistance.
