近年来,利用光量子发生器(激光)进行工件表面热处理的工艺在苏联等国发展迅速。 与其它加热方式相比,激光加热具有以下一些优点:能量高度集中;能局部硬化处理工件难以接触的部位;工件无挠曲和变形;能在长达100米的距离内传递能量。此外,激光热处理无需淬火介质。 由于现代化激光设备可以实现热处理工艺过程的完全机械化和自动化,因此,可以从本质上提高劳动生产率和改善操作人员的劳动条件。
In recent years, the use of light quantum generator (laser) for the workpiece surface heat treatment process in the Soviet Union and other countries to develop rapidly. Compared with other heating methods, laser heating has the following advantages: High energy concentration; Can be hardened to deal with hard-to-reach parts of the workpiece; No deflection and deformation of the workpiece; Can transmit energy up to a distance of up to 100 meters. In addition, the laser heat treatment without quenching medium. Because modern laser equipment can fully mechanize and automate the heat treatment process, labor productivity can be essentially improved and the working conditions of the operator can be improved.
