前言齿轮模具表面强化是指在数控环境下,利用高能量密度的激光束,涂料,熔覆材料对齿轮或模具表面进行处理,改变其表层的组织和成分,实现表面相变,增强性修复的技术。所谓激光相变强化,是用激光束扫描工件,使工件表层快速升温到 Preface Gear mold surface hardening refers to the use of high energy density laser beam, paint, cladding materials on the gear or mold surface treatment, changing the surface of the organization and composition, to achieve the surface phase change, enhanced repair technology. The so-called laser phase transition hardening, is the use of laser beam scanning the workpiece, so that the workpiece surface quickly warmed to
