Thermal spray technology, in which particle melted by discharge plasma or other heating process deposits and forms a coating layers onto material, is already used widely in the fields such as structure bodies of bridge or steel tower, the chemical plant and so on in order to improve abrasion resistance, chemical resistance and corrosion resistance. Because the characteristics of the produced film greatly depends on the temperature and the velocity of the molten particle, the development of a standard particle parameter measurement system has been strongly desired for achievement of the high performance and high quality of the film, and for the appropriate control of the process. In this study, a compact and low-cost measurement system has been developed for a plasma spray process in particular.
