使用粒子诊断系统DPV-2000在大气等离子喷涂过程中研究了飞行中ZrO 2 -7%Y 2 O 3 粒子的性质。喷涂粉末的沉积效率与喷涂参数和颗粒特性相关。随着电流强度和氩气流量的增加，粒子速度显着增加。随着氩气流量的降低和电流强度的增加，颗粒温度显着升高。在给定的喷涂条件下，氩气流量是沉积效率的唯一关键参数。
The properties of in-flight ZrO 2 -7%Y 2 O 3 particles were investigated using a particle diagnostic system DPV-2000 during atmospheric plasma spraying. The deposition efficiency of spray powder was correlated to spray parameters and particle properties. Particle velocity increased significantly with increasing electric current intensity and argon flow rate. Particle temperature increased significantly with decreasing argon flow rate and increasing electric current intensity. The argon flow rate was the only crucial parameter for the deposition efficiency under the given spray conditions.
