Twin Wire Arc
In the arc spray process, an arc is struck between two continuously fed alloy wires causing the tips of the wires to melt. An air jet atomizing gas is used to strip the molten material off the wires and accelerate the motel particles to the workpiece. Arc spraying is a relatively economical coating with reasonable wear resistance properties. Materials typically applied by arc spraying include stainless steels, Hastelloys, nickel aluminides, zinc, aluminum and bronze.
