| 摘 要： | 为了在42CrMo热处理时使用水基聚合物淬火介质,对不同体积分数的聚烷撑乙二醇类高分子化合物(Aquatensid BW)淬火介质进行了冷却曲线测定,探讨了体积分数对BW淬火介质的影响,在此基础上测定42CrMo的硬度,加以验证体积分数为15%的BW冷却性能。结果表明:预热温度为30℃时,随着BW体积分数增加,最大冷却速度和300℃时的冷却速度逐渐降低;对于尺寸精度要求较高的轴类零件,采用体积分数为15%的BW进行淬火,心部洛氏硬度均在48HRC以上,表层硬度大于52HRC,且零件变形小。

| Abstract: | During the heat treatment of 42CrMo,cooling rates of different volume fraction of the polymer quenchant of Polyalklene Glycols(Aquatensid BW) were measured and the influnce of polymer quenchant volume fraction was studied.The hardness of 42CrMo was measured to test and verify the cooling properties of BW with volume fraction 15%.Results show that the maximum cooling rate and cooling rate at 300 ℃ decrease with the increasing of volume fraction of BW when preheating temperature is 30 ℃.For high-precision of the axle parts,when the volume fraction BW as quenchant is 15% the hardness of the parts reach more than 48HRC in the center and 52HRC at the surface,and the parts have a small deformation. |
