This paper reviews experimental and analytical techniques that examine the efficiency of systems for the injection of powders in plasma jets used in spray coating.描述了喷射器的类型、观察颗粒轨迹和分布的实验技术以及用于研究颗粒、载气和等离子体射流之间的动量和传热现象的数学模型。实验数据来自陶瓷粉末等离子喷涂的众多示例。
This paper reviews experimental and analytical techniques that examine the efficiency of systems for the injection of powders in plasma jets used in spray coating. The types of injectors, the experimental techniques for observing particle trajectories and distributions, and the mathematical models used to investigate the momentum and heat-transfer phenomena between particles, carrier gas, and plasma jet are described. Experimental data are presented from numerous examples from the plasma spraying of ceramic powders.
