Investigation of the process of wire arc spraying

Abstract

In the arc spray the metalic wires is melted by means of an electric arc. The molten material is atomized by compressed air and propelled towards the workpiece. The molten spray solidifies on the component surface and form a dense, strongly adherent coating suitable for corrosion protection or component reclamation. Sprayed coatings may also be used to provide wear resistance, electrical and thermal conductive coating or for production of free-standing shapes.
