General Maintenance of Arc-Spray Thermal Spray Equipment

摘要

A twin wire thermal-spray system operates by establishing and maintaining an arc between two metalizing wires that are fed through a spray head at a controlled rate.The molten metal is propelled with compressed air and deposited on a prepared surface.A low voltage,high amperage,direct current power source is required to maintain the electric arc.An air supply is required to propel the molten metal to the surface to be metalized.
