非载气式激光同轴送粉试验研究
Research on New Coaxial Feed Laser Cladding without Carrying Gas
【摘要】 研制了一种非载气式激光同轴送粉系统 ,粉末流能汇聚输出 ,其焦点尺寸为 1 5mm ,焦距 fp15~ 35mm连续可调。在二维平面上熔敷消除了方向性影响 ,多层激光熔敷组织、成分及硬度分布均匀。与载气式同轴送粉相比 ,具有较高的粉末利用率 (6 0 %~ 80 % )及较高的工业应用价值
【Abstract】 A new coaxial feed laser cladding system without carrying gas is researched. Its technical characteristics are as follows: the diameter of focused powder stream about 1.5 mm, focusing length from 15 to 35 mm adjustable,omnidirection, open space and covenience for operating, uniform distribution of microstructure, chemical contents and microhardness, as well as high powder efficiency about 60%~80%.
