A coating of blue-black or black zirconium of uniform and controlled thickness on a zirconium or zirconium alloy material is accomplished through the treatment of an amorphous zirconium or zirconium alloy substrate, which may have an altered surface roughness. The treatment of amorphous zirconium or zirconium alloy substrates includes oxidation of the substrates. A zirconium coating of uniform and controlled thickness is especially useful in various applications because the uniformly thick zirconium surface of controlled depth provide a barrier against implant corrosion caused by ionization of the metal substrates.

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. 1. A chromium-rich cathodic arc coating comprising;a MCrAlY cathodic arc coating on a substrate, wherein M is a metal alloy comprising nickel, cobalt, iron, or a combination thereof, and the cathodic arc coating comprises Si and 25 to 50% chromium by weight based on the weight of the MCrAl; anda diffused chromide coating atop the MCrAlY cathodic arc coating, wherein the diffused chromide coating has a higher content of chromium than the MCrAlY cathodic arc coating, the combined thickness of the diffused chromide coating and the MCrAlY cathodic arc coating is 2.5 to 3 mil (0.0635 to 0.0762 mm) and the chromium-rich cathodic arc coating has a chromium rich phase with a depth of 0.1 to 2.5 mils (0.00254 to 0.0635 mm).2.

A system and method are detailed for aluminizing surfaces of metallic substrates, parts, and components with a protective alumina layer in-situ. Aluminum (Al) foil sandwiched between the metallic components and a refractory material when heated in an oxidizing gas under a compression load at a selected temperature forms the protective alumina coating on the surface of the metallic components. The alumina coating minimizes evaporation of volatile metals from the metallic substrates, parts, and components in assembled devices that can degrade performance during operation at high temperature.
