本文介绍了一种新的热处理方法。其原理是利用高能量密度电子束加热,靠工件本身冷却进行淬火。这种淬火方法特别适用于形状复杂零件的局部淬火。文中介绍了淬火原理和设备,分析了淬火层性能和影响因素,还介绍了在汽车零件上的应用情况,并与激光淬火作了比较。 This article describes a new method of heat treatment. The principle is the use of high energy density electron beam heating, cooling by the workpiece itself quenching. This quenching method is especially suitable for the partial quenching of complex shape parts. In this paper, the principle and equipment of quenching are introduced, the performance and influencing factors of quenched layer are analyzed, the application in automobile parts is also introduced, and compared with laser quenching.
