Title:
CORROSION RESISTANT METAL AND METAL ALLOY COATINGS CONTAINING SUPERSATURATED CONCENTRATIONS OF CORROSION INHIBITING ELEMENTS AND METHODS AND SYSTEMS FOR MAKING THE SAME
Document Type and Number:
WIPO Patent Application WO/2014/169222
Kind Code:
A3
Abstract:
A method and apparatus for producing a corrosion inhibiting coating for metal and metal alloy substrates. The coating is comprised of a metal or metal alloy that is similar in composition to the substrate to be coated, further combined with a corrosion inhibiting material. The corrosion inhibiting material may be a refractory metal or metalloid. The method and apparatus for producing the coating allows for the corrosion inhibiting coating to have a supersaturated concentration of the corrosion inhibiting material alloyed with another metal or metal alloy. The method and apparatus allow for the selective vaporization of material sources to make the coating vapor, which are then entrained in a high speed gas flow that directs the coating vapor onto the substrate. Optional plasma assistance and application of a voltage to the substrate may be used. The coating may be customized for a variety of applications.
