中锰白口铸铁是适应我国资源和生产条件而研究发展的抵抗磨料磨损材料。由于其优异的经济效益和生产便利,已成功地用于制做砂浆泵体和分级机衬铁等矿山易磨件。 本文根据不同成分及热处理的中锰白口铸铁在各类磨料磨损试验机上测试的结果讨论组织对抗磨性的影响及此影响与各类磨料磨损的机制的关系。 低应力冲刷磨损的测试是在混砂盘及橡胶轮两种磨损试验机进行。高硬度的马氏体-碳化物组织最抗磨。脆性相的存在对抗磨性不利。硼加入中锰白口铸铁能使碳化物显微硬度和宏观硬度增加,但使强度和韧性降低。硼适量加入对抗磨性有利。这与此类磨损是宏观冲刷磨损机制有关。 高应力碾研磨损的测试是用肖盘对磨和三体滚轮挤轧两种磨损方式进行。抗磨性与硬度和韧性有关,但基体组织的显微硬度时常起决定性影响。中锰白口铸铁采用Cu Cr Mo综合合金化提高淬透性。残留奥体量大对抗磨性不利。这与此类磨损是以显微切削磨损机制为主有关。 最后小能量多次冲击磨损的测试是以冲头连续冲撞方式进行。抗磨性与材料的冲击韧性有很大关系。低碳含量,稀土变质处理改变碳化物为断开分布的板块状都可起有利影响。这是由于形变磨损机制在这类磨损中起主要作用。 如此可以得出结论,抗磨材料的最合适的组织与磨料磨损的类别和其 Medium manganese white cast iron is to adapt to China’s resources and production conditions and research and development of abrasive wear resistant materials. Because of its excellent economic efficiency and production facilities, has been successfully used in the manufacture of mortar pump and classifier liner iron mine wear parts. In this paper, according to the different composition and heat treatment of white manganese cast iron in a variety of abrasive wear test machine test results discuss the impact of the organization on the anti-wear and the impact of this relationship with various types of abrasive wear mechanism. Low stress erosion wear test is carried out in the sand wheel and rubber wheel wear test machine two. High hardness martensite - the most wear-resistant carbide organizations. The presence of a brittle phase is detrimental to abrasion resistance. Boron added to the manganese white cast iron enables carbide microhardness and macroscopic hardness increases, but the strength and toughness decreased. Addition of boron is good for abrasion resistance. This is related to such wear and tear as a macroscopic erosion mechanism. High-stress grinding wear test is to use Shaw on the three-wheeled roller mill and two kinds of wear and tear wear. Abrasion resistance and hardness and toughness, but the matrix microstructure hardness often play a decisive role. Medium manganese white cast iron with Cu Cr Mo alloying to improve hardenability. Large amount of residual Austrian body wear resistance adversely. This is related to such wear and tear with a micro-cutting wear mechanism. The last small energy multiple impact wear test is based on continuous punch collision mode. Abrasion resistance and material impact toughness has a lot to do. Low-carbon content, rare earth metamorphic treatment to change the distribution of carbide carbide plate can have a beneficial effect. This is due to the fact that deformation wear mechanisms play a major role in this type of wear. It can be concluded, therefore, that the most appropriate tissue and abrasive wear categories for anti-wear materials and their
