SELECTIVE SURFACE FINISHING FOR CORROSION INHIBITION VIA CHEMICAL VAPOR DEPOSITION
A versatile, thermally stable and economically effective corrosion inhibition treatment for copper (Cu) metal and selected metals surface through a single step chemical vapor deposition (CVD) of selected inhibitor compounds at temperatures as low as 100-200 C. is described in this invention. The resulting CVD deposited inhibition coating is thermally stable to 300 C. and protects Cu and selected metals from active corrosion in various technologically important operational environments. The selective coating for copper metal is achieved by controlling the chemistry of bonding between the Copper metal surface and inhibitor material used. The technique can be accomplished by using one or more inhibitors separately or in combination in order to create an all-terrain stable & robust corrosion prevention coating for copper metal.
