Claim 1
Independent Claim
111 words
A METHOD OF PRODUCING INTEGRAL METAL SHAPES BY GAS PLATING WHICH CONSISTS IN THE STEPS OF PROVIDING A SHAPE FROM CELLULOSIC MATERIAL WHICH IS COMBUSTIBLE AT A RELATIVELY LOW TEMPERATURE, APPLYING A COATING FILM THEREOVER WHICH IS HEAT CONDUCTIVE, HEATING THE RESULTANT COATED-SHAPE UNDER REDUCED ATMOSPHERIC PRESSURE CONDITIONS TO A TEMPERATURE TO CAUSE A GASEOUS METAL COMPOUND BROUGHT INTO CONTACT THEREWITH TO BE DECOMPOSED, CONTACTING THE HEATED COATED-SHAPE WITH A GASEOUS METAL COMPOUND WHICH DECOMPOSES DEPOSITING THE METAL CONSTITUENT AS A COATING THEREON, AND CONTINUING THE DEPOSITION OF METAL TO BUILD UP A RELATIVELY THICK COATING OF METAL, AND THEN BURNING AWAY THE CELLULOSIC MATERIAL TO PROVIDE A COMPLETED METAL SHAPE.
