激光淬火是非常有前途的强化机床零件表面的新方法,和惯用的表面强化方法(高频淬火、渗碳、氧化)比较,它具有一系列优点。譬如,激光淬火保证普通碳钢和低合金钢零件高硬度和高耐磨性,某些工况下当零件工作表面可以局部强化时,能够以碳钢和低合金钢取代高合金钢。激光淬火强化的零件变形最小,因而提高制造精度并减小随后机械加工的工作量。此外,在激光淬火高生产率(和惯用的强化方法的生产率相比较)情况下,激光淬火过程和启动激光淬火装置可广泛自动化,包括灵活的生产系统和自动线。激光淬火的机制包括材料处理固态下的 Laser quenching is a very promising new method of strengthening the surface of machine tools and offers a number of advantages over the conventional surface hardening methods (induction hardening, carburizing, oxidation). For example, laser quenching ensures high hardness and high wear resistance of ordinary carbon and low-alloy steel parts, and in certain operating conditions, carbon steel and low-alloy steels can replace high-alloy steels when parts work surfaces can be partially strengthened. Laser quench-hardening parts minimize distortion, thus improving manufacturing accuracy and reducing the amount of subsequent machining. In addition, the laser quenching process and the start-up laser quenching device are widely automated, including flexible production systems and automated lines, with high laser quenching productivity (compared to the productivity of conventional strengthening methods). The mechanism of laser quenching includes material handling in solid state
