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.
