一、前言 热处理是机械零件获得良好性能、提高产品综合性能和使用寿命的重要手段。传统的热处理原始淬火介质,一是水介质,二是油介质。鉴于它们本身的缺陷,性能单一和低能,在热处理工艺过程中,对被淬火件往往带来很多下利影响和危害,如:变形大且不容易校形;淬火残余应力大;尺寸稳定性差;引起最坏的晶界腐蚀;冷却能力卞能适应不同工件、不同材质的性能要求;易产生锤击效应等等。 First, the preface Heat treatment is the mechanical parts to obtain good performance, improve product performance and service life of an important means. The traditional heat treatment of the original quenching medium, one aqueous medium, the second is the oil medium. In view of their own defects, the performance of a single and low energy, in the heat treatment process, the quenched parts are often brought a lot of downside and harm, such as: large deformation and difficult to shape; quenching large residual stress; poor dimensional stability; Causing the worst grain boundary corrosion; Bian cooling ability to adapt to different parts, different materials performance requirements; easy to produce hammering effect and so on.
