摘　　要：聚合物淬火介质冷却金属时于金属表面形成一层聚合物隔离膜,45钢和40Cr钢在不同浓度介质中淬火,可得到比水淬、油淬更大的淬透深度和更小的淬火变形,并可防止淬火开裂。淬火后的组织正常,机械性能符合要求。故表明,此种介质用于钢铁零件淬火非常有效。本文还对使用中的一些管理问题进行了阐明。YWhen the 45 and 40Cr steel parts were quenched in a medium with different concentrations, an isolating polymer film can be formed on the metal surface during the cooling cycle, which resulted in deeper hardening depth and less distortion than those quenched in wate-or oil. Quenching crack can also be prevented. In addition, normal microstructure and satisfactory mechanical properties can be reached.Test results show that these quenchants are particularly effective for the quenching of steel parts. This paper finally elucidates some of the managing problems of CH-202M quenchant in practical use.
