Arc spraying process
Shot, also known as thermal spraying or spray welding, the basic principle is to heat and melt the material (powder or wire), impact on the surface of the substrate (or workpiece), accumulate, solidify to form a film thickness or coating at high speed. , to achieve anti-corrosion, anti-rust, wear-resistant, lubrication, surface roughening, adsorption, insulation, heat insulation, etc.
Arc spraying uses an arc that is burned between two continuously fed wires to melt the metal, atomizes the molten metal with a high velocity gas stream, and accelerates the atomized metal particles to spray them onto the workpiece to form a coating. technology. Arc spraying is one of the most commonly used thermal spraying methods in practical applications such as steel structure corrosion protection, wear resistance and mechanical parts maintenance. The arc spray coating system is generally composed of a spray-dedicated power source, a control device, an arc spray gun, a wire feeder, and a compressed air supply system.
