从六十年代初开始,激光已由实验室中的“珍品”而发展成为尖端的工业工具。起初,这种新工具主要用于工业上的钻孔和切割。但是随着健全可靠的高能激光装置的逐步发展,现在激光已经用于焊接和表面处理。在工业上激光淬火是一种经济可行的金属加工工艺,并且能直接与较低花费的常规工艺如感应淬火相竞争。 鉴于激光束的限域度和高能密度,使它不同于大多数的常规热源。它不应该认为是“整体”热处理,例如沉淀硬化、球化、正火及其它整体淬火工序等。因此,多数工业
Since the early 1960s, lasers have evolved from state-of-the-art “treasures” in the lab into cutting-edge industrial tools. Initially, this new tool was mainly used for drilling and cutting in industry. However, with the development of sound and reliable high-energy laser devices, lasers have been used for welding and surface treatment. Laser quenching in the industry is an economically viable metalworking process and can compete directly with less expensive conventional processes such as induction hardening. Given the confinement and high energy density of the laser beam, it differs from most conventional heat sources. It should not be considered as a “whole” heat treatment, such as precipitation hardening, spheroidization, normalizing and other overall quenching processes. Therefore, most industries
