Abstract: A method of applying a trivalent chromium or chromium-free conversion coating to a metallic substrate including mixing a dye compound that interacts with electromagnetic radiation outside the human visual spectrum but not electromagnetic radiation that is within the human visual spectrum to produce an observable emission into the trivalent chromium or chromium-free conversion coating mixture to allow for inspection of the coating after applied with a correlating electromagnetic radiation source.

Abstract: A method of depositing a high entropy metal alloy coating onto a substrate includes mixing metallic salts of one or more elements with a solvent to form a mixture, heating the mixture to form a liquid, such that constituents of the liquid are in a mobile ionic state, and electroplating the metallic salts onto a substrate from the ionic liquid. A solution for electroplating is also disclosed.

Abstract: In one aspect, a coating for protecting a component exposed to a corrosive environment includes an epoxy phenolic resin, a non-chromated corrosion inhibitor pigment additive and a dispersing agent. In another aspect, a method of protecting an article exposed to a corrosive environment includes applying a corrosion-resistant epoxy phenolic coating to a surface of the article exposed to a corrosive environment and curing the corrosion-resistant epoxy phenolic coating. The epoxy phenolic coating contains up to 15 percent by volume of a non-chromated corrosion inhibitor pigment additive having a particle size less than 10 micrometers.

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.
