With techniques of vibrating focusing beam and automatic powder feeding, a faultless laser cladding layer of Ni based alloy with single track width of 12 mm and thickness of 0.

利用振荡聚焦光束和自动送粉技术 ,获得单道宽 12mm以上、组织致密无缺陷的镍基合金激光熔覆层 ,并对其硬度分布、组织及成分进行了分析和测

On the basis of an analysis on the feeding pattern of the coating material and its behavior in the laser beam during the process of laser coating with automatic powder feeding, a heat equilibrium equation was established and expressions relating the parameters in the process were obtained.

在分析自动送粉式激光熔覆过程中熔覆材料颗粒加入方式及其在激光束中的行为的基础上，建立热平衡方程，推导出反映熔覆过程实际情况的参数：熔覆材料颗粒尺寸、在激光束中运动距离、加热温度、激光功率密度之间的相互关系式等。
