Arc zinc spraying is a metal surface anti-corrosion spraying technology. It uses double-line arc spraying. The arc generated by short-circuiting a direct current power supply melts the zinc wire, and then the high-pressure gas produced by an air compressor sprays the melted zinc ions onto the metal surface, forming a zinc ion protective film on the protected workpiece. The working principle is described as follows: Two wire materials used for spraying are continuously introduced into the nozzle of the spray gun by the wire feeding mechanism. The two ends of the spray gun are connected to the positive and negative poles of the zinc spraying rectifier. The tips of the wire materials are joined at a certain Angle at the outlet of the spray gun. When the wire feeding machine is connected, the two ends of the wire materials short-circuit at the outlet of the spray gun to generate an electric arc. The high temperature of the electric arc melts the wire materials. If the arc burns stably, the wire feeder continuously pushes the wire forward. The front end of the spray gun is equipped with a nozzle that outputs high-pressure air. Under the action of the air compressor, the compressed air continuously sprays out high-pressure gas. The molten metal particles are atomized under the action of the high-pressure gas flow and are quickly sprayed onto the surface of the substrate and solidified to form a coating. The process of arc spraying can roughly be divided into three parts: the melting and atomization stage of the wire material; The flight stage of molten metal particles; The particles are sprayed onto the substrate and enter the stage of accumulation and solidification. Controlling the movement speed of the wire feeding mechanism can alter the DC output current, thereby changing the size of the molten metal particles sprayed onto the workpiece.
