80年代初,已经有关于深冷处理可以使工具钢及某些不锈钢制品的耐磨性和使用寿命提高几倍的报道.后来,美、前苏联、日等国已将这种新技术应用于刀具、模具、量具、齿轮、涡轮轴、弹簧等工件的强化处理,取得了很好的经济效益.但是,对低温强化的机理研究工作却开展得很少,限制了它的进一步发展.对这种处理的必要性、可靠性也存在一定的争论.近几年,国内一些单位也开展了深冷处理工艺的实验研究工作,并通过十几个厂家对各种高速钢
In the early 1980s, there have been reports that cryogenic treatment could increase the wear resistance and service life of tool steel and certain stainless steel products several times. Later, the United States, the former Soviet Union, Japan and other countries have applied this new technology to the tool , Molds, gauges, gears, turbine shafts, springs and other parts of the strengthening treatment, and achieved good economic benefits.However, research on the mechanism of low temperature strengthening has been carried out very little, limiting its further development.To this The necessity of treatment, there is also some debate on the reliability of the argument.In recent years, some domestic units also carried out experimental research work cryogenic treatment process, and through a dozen manufacturers on a variety of high-speed steel
