目前各种淬火剂的介质已广泛应用聚合物的溶液。这些淬火剂的冷却能力介于水和油之间。近年来,英国、西德、法国、比利时、美国、日本和东德都研制了在水里加入有机盐和无机盐做介质的新型淬火剂,取得了良好效果。如美国采用15.3％的聚 At present, a variety of quenching agent media have been widely used polymer solution. The cooling capacity of these quenchanes is between water and oil. In recent years, the United Kingdom, West Germany, France, Belgium, the United States, Japan and East Germany have developed a new quenching agent in the water by adding organic salts and inorganic salts as media, and achieved good results. Such as the United States using 15.3% poly
