产品名称：Arc wire spray

its principle is to start up electric arc through short circuit of two metal wires which have different electric charge.The highheat energy of electric arc melts metal wires and the high speed compressed air atomizes the metal wires into droplet,and accelerates the droplet onto workpiece surface which has be pretreated,then perfect coating is formed. Because of it is easy of use ,the low cost and suitable for large area steel corrosion,rollers are worn repair,special performance work piece and so on.
