Abstract: A non-line-of-sight (NLOS) coating process is provided for a substrate having first and second transverse surfaces where the second surface lacks a LOS for depositional processing. The NLOS coating process includes electroplating or electroless plating a crack-resistant interlayer coating to at least the second surface and applying a wear-resistant coating to the crack-resistant interlayer coating by electrolytic or electroless plating.

Abstract: A method for forming a trivalent chromium coating on an aluminum alloy substrate includes adding a chromium-containing solution to a vessel, immersing the aluminum alloy substrate in the chromium-containing solution, immersing a counter electrode in the chromium-containing solution, and applying an electrical potential bias to the aluminum alloy substrate with respect to its equilibrium potential to form a trivalent chromium coating on an outer surface of the aluminum alloy substrate. A method for forming a trivalent chromium coating on a metal substrate includes adding a chromium-containing solution to a vessel, immersing the metal substrate in the chromium-containing solution, immersing a counter electrode in the chromium-containing solution, and modulating an electrical potential difference between the metal substrate and the counter electrode to form a trivalent chromium coating on an outer surface of the metal substrate.

Abstract: A method includes providing a workpiece with at least one surface having an anodized aluminum coating and a trivalent chromium sealant. The at least one surface of the workpiece is submerged in a post-treatment sealant solution for 0.5 to 20 minutes. The sealant composition consists essentially of a corrosion inhibitor formulation, a water soluble polymer, an organic complexing agent, and an oxidant. The corrosion inhibitor formulation is formulated from at least one anodic corrosion inhibitor compound, at least one cathodic corrosion inhibitor compound, or a combination thereof. A concentration of each of the corrosion inhibitor formulation, the water soluble polymer, the organic complexing agent, and the oxidant is each in a range of 1-50 mM.
