Mn和CE对蠕墨铸铁组织及其摩擦磨损性能的影响
Effect of Mn and CE on the Microstructure and Tribological Characteristics of Compacted Graphite Cast Iron
【摘要】 采用自制的摩擦磨损实验机,对不同碳当量及不同Mn含量的蠕墨铸铁的摩擦磨损性能进行了研究。结果表明:含Mn量0.9%~1.5%、基体以珠光体为主的蠕墨铸铁具有较高的摩擦系数和较小的磨损率,碳当量以不高于4.2%为宜。
【Abstract】 The tribological characteristics of compacted graphite cast iron with different CE and Mn content were investigated by self-made block-disk tester. The results indicate that the C.G. iron containing 0.9%~1.5%Mn,less than 4.2% CE,and with pearlite-base has high friction confficient and low wear rate.
