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.

Abstract: An article is disclosed that includes a first substrate of a first metal or metal alloy. An aluminum alloy first layer on a surface of the first substrate includes is galvanically less noble than the first metal or metal alloy. The first layer can also include elements alloyed with or in solid solution with the aluminum alloy, or can include a two or more phase composition including a first phase of aluminum and a second phase of a solid lubricant.

Abstract: A method for making an environmentally-safe chromium based corrosion resistant coating includes pre-treating a metal substrate, immersing the metal substrate in a trivalent chromium bath which does not contain hexavalent chromium, post-treating the coated metal substrate with an oxidizer, and curing the coated metal substrate in a controlled environment.
