系统地研究了WF150不锈钢合金粉同步送粉激光熔覆工艺参数对熔覆层宏观质量的影响.重点讨论了一些复合参数,如比能(P/VsD)、线能量(P/Vs)、绝对送粉量(Vg/Vs)对熔覆层宏观质量的影响规律.结果表明,在本实验条件下,熔覆层的宽度主要取决于光斑直径,厚度主要取决于单位长度上粉末的实际注入量,即绝对送粉量.熔覆层的宽度、厚度及接触角随比能或线能量的变化遵循对数变化规律.形状系数随比能或线能量的变化遵循幂函数规律.以线能量来表示复合工艺参数比以比能来表示更加合理.
The effects of laser cladding parameters on the macroscopic quality of the cladding layer were systematically studied, and some composite parameters such as specific energy (P / VsD), linear energy (P / Vs), absolute The results show that under this experimental condition, the width of the cladding depends mainly on the diameter of the spot, and the thickness depends mainly on the actual amount of powder injected per unit length , That is, the absolute amount of powder feeding.The cladding layer width, thickness and contact angle with the specific energy or linear energy changes follow the law of logarithm changes in shape factor with the specific energy or linear energy law follows the power function.With the line energy It is more reasonable to express the composite process parameters than the specific energy.
