THERMALLY DEPOSITING A COMPOSITE COATING ON ALUMINUM SUBSTRATE

Method of depositing an FexO comprising coating onto a light metal substrate by use of wire-arc thermal spraying that propels atomized drouplets by use of atomizing gases, comprising: preparing at least one surface of the light metal substrate to present an exposed essentially non-oxidized substrate...

Beschreibung
Zusammenfassung:	Method of depositing an FexO comprising coating onto a light metal substrate by use of wire-arc thermal spraying that propels atomized drouplets 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 .5-1.5.
