2Cr3WMoV铸钢件渗氮工艺的研究
Research on Nitriding Processes of 2Cr3WMoV Cast Steel
【摘要】 对2Cr3WMoV铸钢件在预备热处理(1050℃空冷+750℃空冷+1050℃油冷+680℃空冷)基础上进行渗氮工艺试验,选择的温度是540℃、560℃、580℃。在560℃下保温时间为37h、45h、50h,试验结果表明在560℃,时间37~50h表层硬度>HV940,渗层深度0.45mm~0.65mm。
【Abstract】 Based on the preheat treatment(1 050 ℃air cooling+750 ℃ air cooling+1 050 ℃ oil cooling +680 ℃ air cooling)of 2Cr3WMoV, this paper deals with the nitriding processes of technology of 2Cr3WMoV at 540℃, 560 ℃, 580 ℃, and different holding time(37 h, 45 h, 50 h)for 560 ℃. The result shows that its surface hardness is stronger than HV 940 and depth of nitriding is 0.45 mm~0.65 mm.
