ring forging

The result of test indicates 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.

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。
