    Experimental Study on Particle Characteristic of HVOF Sprayed WC-10Co4Cr

      摘要
    • 摘要: 采用DPV-eVOLUTION型热喷涂监控装置对超音速火焰喷涂WC-10Co4Cr过程中的粉末粒子特性进行研究，重点分析喷涂工艺参数对火焰中粒子的温度、速率的影响规律。结果表明：粒子速率、粒子温度和粒子直径并不沿火焰中心线对称分布；在喷涂过程中，直径较小的颗粒可以获得更高的速率；当喷涂距离增加时，粒子的速率和温度均存在极大值；气体流量的增加导致粒子温度和速率同时提高。

       

      Abstract: The DPV-eVOLUTION thermal monitoring device was adopted to study the characteristics of WC-10Co4Cr powder particles during HVOF spraying. The influences of the spraying process parameters on temperature and speed of the particles in the flame were mainly analyzed. The results show that the particle velocity, particle temperature and particle size don’t symmetrically distribute along the center line of the flame. During spraying, the smaller diameter of the particles could obtain a higher speed. When the spraying distance was increased, the speed and temperature of the particles would present maximum. Both the particle velocity and temperature were improved with the gas flow increased.
