Abstract: A process includes applying a slurry to a surface of a metallic article to produce a slurry film on the surface. The slurry is composed of a liquid carrier, chromium and aluminum, and an agent that is reactive with the chromium and aluminum to form intermediary compounds. The article and slurry film are then thermally treated at an activation temperature at which the agent reacts with the chromium and aluminum to form the intermediary compounds. The intermediary compounds deposit the chromium and aluminum on the surface. The thermal treating also diffuses the chromium and aluminum into a sub-surface region of the article such that the sub-surface region becomes enriched with chromium and aluminum.

Abstract: A process for applying a chromized layer on a substrate by first applying an overlay coating to a portion of the substrate, and subsequently contacting a different portion of the substrate and the overlay with a gas containing gaseous chromium, wherein the gaseous chromium can be generated from a chromium source and an activator. The process prepares the substrate, often a jet engine airfoil, for service.

Abstract: The present invention provides a Cr-rich cathodic arc coating, an article in turbine blade coated with the chromizing over cathodic arc coating, and a method to produce the coating thereof. The Cr-rich cathodic arc coating in the present invention comprises a cathodic arc coating and a diffusion coating deposited atop the cathodic arc coating to enforce hot corrosion resistance. The hardware coated with the chromizing over cathodic arc coating in the present invention is reinforced with superior-hot corrosion resistance. The present invention further provides a novel method for producing the chromizing over cathodic arc coating by re-sequencing coating deposition order. The method in the present invention is efficient and cost-reducing by eliminating some operations, e.g., DHT and peening, between the cathodic arc coating and the diffusion coating. The hot corrosion resistance in the present invention results from the high Cr content in the surface of the coating.

Abstract: A process for coating a gas turbine engine airfoil comprising coupling the airfoil having an internal surface with a chamber, the chamber configured to perform atomic layer deposition; injecting a first reactant into the chamber; forming a first monolayer gas thin film on the internal surface; removing the first reactant from the chamber; injecting a second reactant into the chamber; forming a reaction with the first monolayer gas film to form a solid thin film; removing the second reactant from the chamber; and forming a protective barrier coating on said internal surface.

Abstract: A method for chromizing an article includes applying a slurry to an article. The slurry has active chromium and a residue-removal agent. The method also includes heating the article and slurry to diffuse chromium from the slurry into the article. The heating leaves a residue on the article with the residue-removal agent. The heating also includes removing the residue-removal agent to thus remove the residue from the article, using a cleaning solution. A method for chromizing parts and a method of cleaning a chromized part are also disclosed.
