Abstract:
1. A method of coating an interior metal surface of a gas flow control component with a corrosion resistant thin film, comprising the steps of: placing a predetermined amount of a corrosion resistant precursor gas within the interior of the gas flow control component; sealing the precursor gas within the interior of the gas flow control component; placing the gas flow control component inside an oven; heating the gas flow control component inside the oven sufficiently to cause the precursor gas to thermally decompose into a gas phase intermediate product and a gas phase organic product and form a thin corrosion resistant film on the interior metal surface of the gas flow control component when the precursor gas thermally decomposes and forms an absorbate on the interior metal surface of the gas flow control component; and withdrawing the gas phase organic product from the interior of the gas flow control component.
