一、项目简介在普通钢材表面,通过特殊的粉末冶金方法烧结一层块状硬质材料或超硬质材料,形成一个耐磨性极好的工作表面。这种工艺方法可用来制作硬对硬的滑动摩擦副。这种硬对硬的滑动轴承可不用密封,其润滑介质可以用流动水、皂化液、机油及其他含砂液体,其耐磨性比现有的任何轴承材料都高。 I. Introduction to the Project On the surface of ordinary steel, a layer of hard or super hard material is sintered by special powder metallurgy method to form a work surface with excellent wear resistance. This process can be used to make hard and soft sliding pair. This hard-to-hard plain bearings can be unsealed, the lubricating medium can use flowing water, saponification liquid, oil and other sand-containing liquid, the wear resistance than any existing bearing materials are high.
