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.

Abstract: The present disclosure relates generally to a fan blade assembly. In an embodiment, the fan blade assembly includes an airfoil having a forward edge covered by a sheath. The airfoil and the sheath are made from dissimilar conductive materials. A sacrificial anode layer is applied to at least a portion of the sheath so that the sacrificial anode layer will corrode instead of the airfoil.

Abstract: During a material removal method, a component is received that includes a component body and a coating on the component body. The component body includes metallic first material. The coating includes second material that is different from the first material. A solution is received that includes nitric acid and hydrogen peroxide. At least a portion of the coating is subjected to the solution in order to remove at least some of the second material from the component.

Abstract: A method of assessing galvanic electronic isolation of two components at a joint of the two components includes measuring a first electrical resistance at a first condition across a joint of two components and comparing the first electrical resistance to a threshold resistance. The comparison of the first electrical resistance to the threshold resistance is indicative of a degree of electrical isolation of the two components. A second electrical resistance is measured at a second condition and the second electrical resistance is compared to the first electrical resistance. The result of the comparison of the second electrical resistance to the first electrical resistance is indicative of a type of electrical connection between the two components.

Abstract: A metal article comprises an alloy substrate having a surface and a non-diffused metal monolayer disposed thereon. The surface has a first surface work function value Φs. The non-diffused monolayer deposited on the surface has a second surface work function value Φs that is less negative than the first surface work function value. A method for depositing the monolayer via underpotential deposition (UPD) is also disclosed.
