Explosive spraying is to first send a certain proportion of oxygen and acetylene from the air supply port to the combustion chamber of the cold spray gun, ignite through the spark plug, explode combustion of oxygen and acetylene mixed gas, and then send the spray powder into the combustion chamber by the powder feeder. The thermal energy heats the sprayed powder to a certain state, and finally sprays the powder particles onto the surface of the workpiece under the action of the explosion shock wave to form a coating.
Explosive spraying is a new technology with high technical difficulty and strong process performance, and it is also a high-energy spraying method. Compared to general flame spraying, it is necessary to provide a sufficiently high gas pressure and a large gas consumption.
