PROBLEM TO BE SOLVED: To provide a pulse detonation thermal spray device which is compact, has durability and has high working efficiency, and to provide a thermal spraying method therefor.SOLUTION: The pulse detonation thermal spraying device 10 includes: a combustion cylinder 11 in which one end is closed and the other end is opened; a fuel gas feeding structure 13, an oxygen gas feeding structure 14 and an inert gas feeding structure 15 at the closed end part of the combustion cylinder; an ignition unit 16 performing ignition to the mixed gas of the fed fuel gas and oxygen gas at prescribed operation frequency; a powder feeding structure 18 of feeding powder for thermal spraying to the downstream of the ignition unit 16. The fuel gas and the oxygen gas are oppositely jetted, and the inert gas is jetted toward the closed end part of the combustion cylinder. |
