Abstract
A method of coating a metal article is disclosed that includes immersing a metal article having an exterior anodized layer in a bath containing a chemically active corrosion inhibitor, and applying a voltage to the article during the immersing, the voltage driving the chemically active corrosion inhibitor from the bath into the exterior anodized layer. An article is also disclosed that has a substrate comprising a metal, and a porous anodized layer formed on an exterior surface of the substrate that is infiltrated with a chemically active corrosion inhibitor, the anodized layer having an inward-facing region and an outward-facing region, the anodized layer having a greater concentration of chemically active corrosion inhibitors in the inward-facing region than in the outward-facing region.
