Spraying parts and high melting point metal sprayed film using the same thermal spray and high melting point metal powder

摘要

The thermal spraying high melting point metal powder according to the present invention is 1~10μm average particle size of the primary particles, the average particle size of secondary particles the primary particles adhered is 20~150μm, particle size and wherein the ratio of the secondary particles is 20~150μm is 70 mass% or more of the whole. Moreover, by controlling the density and flowability of the secondary particles. In the case of forming a sprayed coating with the spray refractory metal powder with good film-forming properties handling properties such a good is obtained providing a high melting point metal film having a uniform thickness.
