近年来,在热处理实践中,对开发新的淬火介质以代替传统的水和油,给予很大的关注。大量的研究工作,集中在开发水溶性聚合物基的淬火剂上。所有这类淬火剂都象水和油一样,淬火时必须把零件浸入液体。而这种淬火方法有个非常重大的缺点,即在淬火过程中不能加以控制,不能对淬火冷却过程作必要的修正。此外,依我们的看 In recent years, much attention has been given to the development of new quenchant media to replace traditional water and oil in heat treatment practice. A great deal of research work has focused on the development of water-soluble polymer-based quenchants. All of these quenchants, like water and oil, must be immersed in liquid during quenching. However, this method of quenching has a very significant disadvantage that it can not be controlled during the quenching process and can not be modified as necessary for the quench cooling process. Also, look at us
