Electric Arc Wire Spray
A simple, fast and economical thermal spray process for in-shop or on-site work.
The Electric Arc Wire Spray process uses two metallic wires, usually of the same
composition, as the coating feedstock. The two wires are electrically charged
with opposing polarity and are fed into the arc gun at matched, controlled
speeds. When the wires are brought together at the contact point, the opposing
charges on the wires create enough heat to continuously melt the tips of the
wires. Compressed air is used to atomize the now molten material and
accelerate it onto the workpiece surface to form the coating.
