An electric arc is formed when two wires connected to
different poles come into contact at the spray gun outlet. With the arc, the wires
melt and disintegrate. Coating is performed by spraying the melted and
semi-melted wire particles with the help of compressed air.
Pure metal and metal alloy wires are used as coating
material. (Carbon steels, alloy steels, stainless steels, aluminium, copper,
bronze, cobalt, nickel, molybdenum, tin, zinc)
During coating, the temperature of the workpiece is kept
under control and distortions and dimensional deformation are not allowed.
Coating thickness over 5 mm can be obtained with this system. Coatings with high surface roughness values
are obtained with this system.
Arc Wire Spray coatings give various advantages to the base
material:
