The contact of wires from opposite poles in the spray gun, creates an electric arc. With this arc, wires melt and dissolve into particles. Coating is achieved by the spray of melted or half melted wire pieces with pressured air.

As coating material, pure metal and metal alloy wires are used. (carbon steels, alloy steels, stainless steels, aluminium, copper, bronze, cobalt, nickel, molibdenum, tin and zinc)

n the coating period distortion and dimensional deformation is avoided by controlling the temperature of work piece.

Above 5mm coating thickness can be obtained with this system.  High roughness coatings can be achieved.

Electric arc wire spray coatings brings various advantages to the main material:

• Corrosion resistance
• Obtaining bonding and rough surface
• Good electric and heat conductivity
• Better oxidation and wear resistance
• Higher service temperature
• Higher hardness
• Repairing and diameter restoration
