摘　　要：通过对Ｃｒ１２ＭｏＶ、ＭｎＣｒＷＶ和４Ｃｒ５ＭｏＶＳｉ三种模具钢进行淬火及在不同温度下回火处理，测定硬度值和粘着磨损、磨粒磨损的比磨损量，得到了模具钢回火温度、硬度与比磨损量的关系特性。实验指出，注塑成型模具在工作温度３００℃、热处理硬度ＨＲＣ５５以上的条件下工作，三种模具用钢均表现出良好的耐磨性能。The hardness and wearability (adhesive wear and abrasive wear) of Cr 12 Mov, MnCrWv and 4Cr 5 Movsi steel were determined by quenching and treating in different temper temperatures The relationship of temper temprature, hardness and wearability was pointed out All kinds of the experimental steels showed good wearability in the condition that the injection mold′s temperature is below 300℃ and Rochwedl hardness is above HRc55
