【摘要】 介绍了采用新研制的ＷＧＹ淬火介质替代机械油对中碳合金钢钢板弹簧和汽车螺栓进行淬火冷却的试验结果，并与聚合物淬火介质２８２Ａ、ＡＱ２５１试验结果进行对比。结果表明，采用ＷＧＹ淬火剂处理钢板弹簧、汽车螺栓，其金相组织、淬火硬度、力学性能与油淬相近，疲劳寿命优于油淬，中碳合金钢制零件用ＷＧＹ淬火剂替代机械油淬火是可行的。更多还原

【Abstract】 The WGY water soluble medium is used as a quenching medium in carbon alloy steel spring plates and automotive bolts are used to substitute for quenching oil. Comparisons are made among test results of polymer medium 282A, AQ251 and WGY. The results show that quenching hardness, microstructures, dynamical properties of steel spring plates treated with WGY are similar to those with oil, and the fatigue strength is longer than oils. This medium is used in the quenching of spring plates and automobile bolts as a substitution for oil.更多还原
