在强烈的激光作用下,工件受照表面局部被迅速加热,接着工件离开激光束迅速淬火。这时材料的金相结构会发生变化,凝固成耐磨防锈、硬度和韧性得到提高的材料。根据所用激光照射强度和时间的不同,可以进行各种不同的表面处理: Under intense laser action, the surface of the irradiated part of the workpiece is rapidly heated, and then the workpiece is quickly quenched from the laser beam. At this time the metallurgical structure of the material will change, solidified into a wear-resistant rust, hardness and toughness have been improved material. Depending on the intensity and time of the laser used, a variety of surface treatments are possible:
