| 摘 要： | 评估了水、10%的水溶性聚合物溶液以及常规淬火油对碳氮共渗件的淬火性能,并比较了经各种介质冷却后的淬火态和调质态的显微组织.淬硬层中的典型组织为气体碳氮共渗产物（碳氮化合物）-马氏体-残留奥氏体,心部组织为马氏体-残留奥氏体或贝氏体-残留奥氏体.通过研究残留奥氏体和氮碳化合物的含量对硬度、耐磨性和冲击强度的影响,表明使用10%的水性聚（亚烷基）二醇淬火液淬火时的效果最佳.

| Abstract: | Water, 10% aqueous polymer solutions and a conventional quench oil were evaluated to harden carbonitrided parts. The resulting as-quenched and quenched and tempered microstructures were compared. Typically, the gas carbonitriding process produced (carbonitrides)-martensite-retained austenite in the case and martensite-retained austenite or bainite-retained austenite in the core. The effect of the amount of retained austenite and carbides (carbonitrides) on: hardness, abrasive wear resistance, and impact strength showed that the best results were obtained when a 10% aqueous solution of a polyalkylene glycol quenchant was used. |
