Low power plasma spray process is attracted attention for deposition of coating with reducing microstructure change of coating and substrate. Atmospheric pressure microwave plasma spraying is a new method for fabricating coating under low power below 1kW. The generated plasma temperature exceeded above 4000 K, and was available for plasma spraying of Al, Cu, hy-droxyapatite (HAp), and Cu onto steel substrate below 1kW. Moreover, Cr coating was successfully fabricated by decreasing the nozzle diameter for increase of the particle velocity up to 135.4 m/s. As a result, low power input realized the Cr coating on heat susceptible substrates, such as CFRP and high carbon steel. Also, TiO_2 coating was successfully fabricated with high photocatalytic activity by reducing the heat input to spray particles.
