Popis:	Oxidation behavior of in-flight particle in plasma spray process significantly affects the coating properties and performance. Therefore, understanding the relationship between in-flight particle characteristics and oxidation phenomena is essential to improve the coating properties. This paper presents the oxidation behavior of in-flight aluminum particles and its relationship between in-flight particle temperature and velocity. Aluminum powder was injected into the plasma flame at different spray conditions and collected at different stand-off distances by using a specially designed equipment. It has been observed that in-flight particle velocity is the main parameter that affects the oxidation of aluminum particles.
