      From the basic principle, explosive spraying is another manifestation of thermal spraying. It is a thermal spraying method that explodes the mixed gas in the explosive limit range when the spark plug is ignited, heats, melts the powder material and sprays it on the surface of the workpiece to form a coating. Compared with other forms of thermal spraying technology, the gas jet speed during explosive spraying is higher. Therefore, the compactness of the explosive sprayed coating and the bonding force between the coating and the substrate are better. However, explosive spraying equipment is complicated, expensive, low production efficiency, and serious noise pollution during construction. Therefore, in the field of equipment maintenance, few people use explosive spraying technology.
