摘　　要：采用脉冲激光光屏法对电弧喷涂过程中飞行的粒子场进行了测量 ,得到离喷枪出口不同距离的粒子形态及分布。研究粒子从喷枪喷出后 ,在 3 0 0mm的飞行过程中的尺寸变化及粒子形状的演变进程 ,发现粒子形状持续变化 ,尺寸不断减小。The sizes of flight particles in high\|speed arc spraying process were measured by using camera and pulse laser sheet. The sizes and distribution of particles in different distance away nozzle had been obtained. At the same time, the shapes of the particles were also observed by the method. According to the results, the shapes and average size of particles were continuously changed and the average size was decreased in 300 mm standoff distance.
