模具的激光表面熔敷成型技术及应用

Mold laser deposited on the surface of molding technology and application

激光熔敷制造技术是激光快速成型(激光3D打印)技术的一种,其中采用同轴送粉的激光熔敷制造技术灵活程度高、粉末材料种类多,通过设备、工艺和材料系统的组配,可以形成新的表面熔敷成型技术,重点解决模具局部磨损、腐蚀、崩塌等缺陷的修复和表面结构的近净型成型再制造,也可以方便地在模具局部区域形成具有特殊性能的处理区域,具有广泛的应用前景。

laser deposition manufhcturing technology is laser rapid prototyping （laser 3 d printing） technology, which USES the feeding laser deposition manufacturing technology of flexible coaxial degree is high, powder material variety, by equipping equipment, process and material systems, can form new deposition on the surface of molding technology, the key to solve local wear, corrosion, mold collapse defect repair and surface structure of near net shape forming and manufacturing, also can be easily formed in the mold local processing regions with special performance, has wide application prospect.
