current position：Information and data>What is the principle of arc spraying
Arc spraying is a thermal spraying method in which the arc is used as the heat source, the molten metal wire is atomized with a high-speed airflow, and sprayed to the surface of the workpiece at a high speed to form a coating. During arc spraying, the two wire-like spraying materials are uniformly and continuously fed into the two contact nozzles of the spray gun through the wire feeding mechanism. sex. When the ends of the two wires come into contact, an arc occurs due to a short circuit. The high-pressure air atomizes the metal melted by the arc into micro-droplets and accelerates the spray to the surface of the workpiece to deposit and form a coating. Arc spraying is a continuously repeated melting-atomizing-deposition process.
