摘要

以高铬铸铁为试验原料,利用光学显微镜、扫描电镜、硬度试验机和MLD-10动载磨料磨损试验机等研究不同钼含量对高铬铸铁组织及耐磨料磨损性能的影响。结果表明:Mo的加入达到细化晶粒、改变碳化物形状和分布以及提高淬透性的目的;Mo含量不同磨损量也不同;磨损的主要形式为犁沟与凸缘。
        The effect of molybdenum content on the microstructure and wear resistance of high chromium cast iron was studied by means of optical microscope,scanning electron microscope,hardness tester and MLD-10 dynamic abrasive wear tester. The results show that the addition of molybdenum can refine the grain,change the shape and distribution of carbides and improve the hardenability.The weight lose is different with different Mo content and the main wear deformation forms are ploughing and flange.
