激光工作者与热处理工作者,正在密切合作对激光表面处理进行广泛深入的研究。目前比较成熟的是激光表面相变硬化热处理。在汽车工业中,铸铁激光表面处理的研究最为活跃,已有几项研究成果用于工业生产。展望激光表面处理工业应用的前景,应使1～5kW 的中功率 CO_2激光商品化,发展中的5～20kW 大功率 CO_2激光器,特别要解决寿命和可靠性的问题。随着工业用 CO_2激光器的发展,必将促进激光表面处理在工业生产中的应用。
Laser workers and heat-treatment workers are working closely and extensively on laser surface preparation. Currently more mature laser surface transformation hardening heat treatment. In the automotive industry, cast iron laser surface treatment is the most active research, several studies have been used for industrial production. Looking forward to the prospect of industrial application of laser surface treatment, 1 ~ 5kW medium-power CO_2 laser should be commercialized, and the developing 5 ~ 20kW high-power CO_2 laser should solve the problems of life expectancy and reliability in particular. With the development of industrial CO 2 lasers, it will surely promote the application of laser surface treatment in industrial production.
