An arc spray is a technique of atomizing a metal by burning an electric arc between two successive wires, atomizing the molten metal with a high-speed air stream, and accelerating the atomization of the metal particles onto the workpiece to form a coating The Arc spraying is the most commonly used thermal spraying method for practical applications such as corrosion resistance, wear resistance and mechanical parts maintenance of steel structures. Arc spraying system is generally made by spraying special power supply, control device, arc spray gun, wire feeder and compressed air supply system and so on.
