各种蠕虫状石墨铸铁的使用日益广泛,但马氏体基体蠕铁尚很少被使用。本文介绍了蠕铁的淬硬工艺,初步分析了热处理机理,对比了马氏体基体蠕铁、普通灰铸铁和GCr15钢对磨实验的结果,分析了马氏体基体蠕铁耐磨性高的原因。文中还列举了马氏体基体蠕铁的应用实例,从中可以看出用马氏体基体蠕铁代替GCr15钢的经济和社会效益及其推广应用前景。 A variety of worm-like graphite cast iron is increasingly used, but the martensite matrix of iron is still rarely used. This paper introduced the harden process of vermicular iron, the heat treatment mechanism was analyzed preliminarily, the results of the experiment on the grinding of the martensite matrix compacted iron, the common gray cast iron and the GCr15 steel were compared. The martensite matrix with high wear resistance the reason. The article also lists the application of martensite matrix of iron, from which we can see the use of martensite matrix of iron instead of GCr15 steel economic and social benefits and its promotion and application prospects.
