A METHOD OF GAS PLATING ALUMINUM METAL ONTO SUBSTRATE BY DECOMPOSITION OF AN ARGANO ALUMINUM HALIDE COMPOUND WHICH COMPRISES THE STEPS OF CLEANING THE SUBSTATE TO REMOVE FOREIGN MATTER AND MOISTURE FROM THE SURFACE, HEATING THE CLEANED SUBSTRATE IN AN UNOXIDIZING ATMOSPHERE WHICH IS FREE OF WATER VAPOR, SUBJECTING THE THUS HEATED SUBSTRATE TO AN ATMOSPHERE CONTAINING A HEATDECOMPOSABLE ORGANO METALLIC ALKYL HALIDE COMPOUND OF ALUMINUM, THE TEMPERATURE OF THE SUBSTRATE BEING HIGH ENOUGH TO CAUSE THERMAL DECOMPOSITION OF THE ORGANO METALLIC HLIDE ALUMINUM COMPOUND AND DEPOSITION OF ALUMINUM METAL ONTO SAID SUBSTRATE.
