摘　　要：对镍硬铸铁和常用的铬系白口铸铁进行了削盘磨损试验和冲击磨料磨损试验。结果表明:白口铸铁的抗磨性能与其显微组织有着直接关系,不同成分和组织的铬系白口铸铁的抗磨性能随着磨损条件的变化而变化较大,但一般均优于镍硬铸铁。Abrasion-resistant capability of Ni-cast iron and Cr-cast iron were studied by abrasion wears and impact test. The results show that abrasion-resistant capability of white cast iron lay on the microstructure and properties,and that of Cr-cast iron with the different ingredient and microstructure vary greater with condition, but it was usually better than that Ni-cast iron performed.
