Beschreibung
Zusammenfassung:	The invention discloses a detonation gun spraying method of tungsten carbide. The method comprises the following steps: adjusting the technological parameters of tungsten carbide powder, adjusting the intake speeds of oxygen and acetylene, adjusting the parameters of detonation gun spraying, performing detonation gun spraying, cleaning a gun barrel, performing fine machining, and the like. By adopting the method, the structure uniformity of a coating and the bonding force of the coating and a matrix can be effectively enhanced and the localization of a blade pin special tungsten carbide coating spraying technology can be realized.
