摘　　要：高应力磨料磨损或低应力磨料磨损工况条件下,高铬白口铸铁空淬后不须回火可直接应用。回火造成磨损抗力降低。在反复强力冲击工况条件下,回火得到回火马氏体,抗冲击剥落能力大为增加。Under high stress or low stress abrasion working conditions, high Cr white cast iron can be used just after it having been air quenched. Tempering treatment caused decreasing of abrasion resistance. Tempering treatment resulted in formation of tempered martensite and the spalling resistance under repeated strong impact abrasion working conditions was largely improved.
