Abstract
A method is disclosed for the electric arc spraying of powder-filled cored wires to apply hard, wear-resistant coatings to various substrates. Inert gas, preferably nitrogen, is supplied to the arc spray gun such that the mass ratio of the wire feed rate to the gas feed rate is preferably between about 0.07 and about 0.11. Operation in this range yields an optimum combination of coating hardness properties and arc spray gun operating characteristics.
