The deposit characteristics of ceramic powder sprayed onto a substrate by the gas tunnel type plasma spraying apparatus were studied, and it was found that the special spraying distance L^* can be determined by the deposit characteristics. The relation between the deposit characteristics and the coating quality such as the Vickers hardness and porosity was discussed and it was clarified that the special spraying distance L^* governing deposit characteristics corresponded to the critical spraying distance L_c which indicated the largest distance in order to obtain the good coating quality.
