Method of depositing an FexO 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 FexO is substantially the only iron oxide formed during spraying, x being 0.5-1.5.

A method of depositing an FexO comprising coating onto a light metal substrate by use of wire-arc thermal spraying that propels atomized droplets by use of atomizing gases, comprising: (a) preparing at least one surface of said light metal substrate to present an exposed essentially non oxidized substrate surface; and (b) thermally spraying melted droplets of a low carbon (0.04-2% by wt.) steel feedstock wire onto said prepared surface by use of propellant gases at a gas flow rate of 30-120 SCFM to deposit a composite coating, the gases being controlled as to content to regulate the exposure of said droplets to oxygen so that wustite of the formula FexO (Wustite) is the only iron oxide formed during spraying, x being 0.5-1.5, said coating containing said wustite in amount of 5-30% by volume with the balance being iron based of a composition essentially that of the starting feedstock.
