Abstract
Method of depositing an Fe.sub.x O comprising coating onto a light metal substrate by use of wire-arc thermal spraying that propels atomized droplets by use of atomizing gases, comprising: preparing at least one surface of the light metal substrate to present an exposed essentially non-oxidized substrate surface; and thermally spraying melted droplets of a steel feedstock wire onto the prepared surface by use of propellant gases to deposit a composite coating, the gases being controlled as to content to regulate the exposure of the droplets to oxygen so that Fe.sub.x O is substantially the only iron oxide formed during spraying, x being 0.5-1.5.
