DEVEOPMENT OF THE INSTITUTE :: Wire Arc Coatings
In wire Arc coating, the starting wire feedstock, usually 1/16 in diameter may be composed of essentially any material that can be purchased at this size.
Two wires with an electrical potential are brought together at an angle of about 20 degrees. A current is drawn through the wires and they ?melt? at their point of contact. An atomizing gas propels the molten particles at the substrate at low velocity. PTI applies about 10 different materials by this technique.
