【摘要】 在以显微切削为主要机制的二体磨制磨损系统中，研究了不同铸型条件下碳化物尺寸的变化对高铬铸铁耐磨性的影响。结果表明，高铬铸铁中碳化物相的抗磨作用具有“尺寸效应”，即在碳化物数量一定时，过小的碳化物尺寸将影响碳化物相抗磨作用的发挥，大幅度地降低高铬铸铁的耐磨性。更多还原

【Abstract】 The effect of carbide phase’s sizes obtained in different moulds on the wear resistance of high chromium white cast iron was investigated in two-body abrasion wear system,in which the wear mechanism is predominantly microcutting, It is shown that there was a "size effect" on the wear resistant effect of carbide phase in high chromium white cast iron,that is to say, too small carbide size would affect the wear resistant effect of carbide phase and decrease the wear resistance of high chromium white cast iron greatly under the condition of fixed carbide amount.[更多还原
