摘自《金属热处理》1982年第6期,于志勤、房为捷: 激光热处理仅是一项先进的局部表面热处理新工艺。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,现已有几项研究成果用于工业生产。本文着重介绍了激光器的种类及特征等。文中列举了美国通用汽车公司和阿发科公司,采用激光表面热处理方法,改善和提高用于不同用途铸铁的耐磨等性能试验表明,铸铁经激光热处理后,不仅提高耐磨性,耐腐蚀性能,在节能和减少废品率方面也都优
From “metal heat treatment” 1982 the sixth period, Yu Zhiqin, Fang Weijie: laser heat treatment is only an advanced local surface heat treatment process. Currently more mature laser surface transformation hardening heat treatment. In the automotive industry, cast iron laser surface treatment of the most active research, there are several studies have been used for industrial production. This article focuses on the types and features of lasers. The article lists the United States General Motors and Acco, the use of laser surface heat treatment method to improve and enhance the wear resistance for different purposes cast iron performance test shows that the cast iron by laser heat treatment, not only improve the wear resistance, corrosion resistance , Are also excellent in energy saving and scrap reduction
