众所周知,石墨化的钢具有高耐磨性和抗咬合性,但是,它的机械性能不高,因此,限制了它用于制作承受高动载荷的零件。这类零件可采用低碳含硅钢来制造,而通过在表面获得含石墨的渗层的方法,可以提高其耐磨性。对硅钢进行渗碳并随后进行石墨化退 It is well-known that graphitized steels have high wear resistance and seizure resistance, but their low mechanical properties limit their use to the manufacture of parts subject to high dynamic loads. Such parts can be made of low-carbon silicon steel, and by the surface of the graphite-containing layer of the method, can improve its wear resistance. The silicon steel is carburized and then graphitized
