A fuel rod cladding (4) for a light water reactor includes a core (16) including a matrix consisting of pure molybdenum or of a molybdenum-based alloy; and an outer protective layer (18). The outer protective layer (18) is selected among a chromium-based coating (20) deposited on an outer surface of the core (16) that includes at least one chromium-based coating layer (24) consisting of pure chromium or of a chromium-based alloy; a chromium-based diffusion layer (22) obtained by diffusion of chromium into the core (16) from the outer surface of the core (16); or a succession of a chromium-based diffusion layer (22) obtained by diffusion of chromium into the core (16) from the outer surface of the core (16) and a chromium-based coating (20) consisting of chromium or of a chromium-based alloy deposited on the outer surface of said core (16).

A component includes a diffusion coating comprising an inter-diffusion zone between the diffusion coating and a substrate and a non-metallic inclusions zone adjacent to an outer surface of the diffusion coating. A method of coating a component includes applying an aluminizing slurry to a localized area of a component and applying a chromizing slurry to the localized area of the component subsequent to heat treating the aluminizing slurry.

A mask is used in aluminizing of superalloy turbine component, such as a turbine blade, where a region exposed to relatively high operating temperature is aluminized to form a diffusion aluminide coating and another region exposed to relatively lower operating temperatures is masked to prevent aluminizing of the masked region while concurrently being enriched in Cr and/or retaining a pre-existing Cr-content from the superalloy chemistry itself or from a previous chromizing operation.

Disclosed is a process for producing a high-temperature protective coating for metallic components, in particular components of turbomachines which are subjected to thermal loading. The process comprises producing a slip from MCrAlY powder, in which M is at least one metal, and from a Cr powder, applying the slip to the component to be coated and subsequently alitizing the component provided with the slip.

Disclosed is a process for producing an alloyed, in particular multiple-alloyed aluminide or chromide layer on a component by alitizing or chromizing. First a green compact layer (9) consisting of a binder (5) and metal particles (7) is deposited on the component (1) to be coated and then alitizing or chromizing is carried out, binder and metal particles being deposited on the component separately from one another, first the binder and then the metal particles. A turbine component produced by this process is also disclosed.

A sliding component having a wear-resistant coating includes a sliding component formed of a Ni alloy, and a wear-resistant coating provided on a sliding surface of the sliding component. The wear-resistant coating has, at least on the surface side thereof, an Al-containing Co alloy layer which contains Co as a main component, at least one of W, Ni, Mo, Fe, Si, and C, Cr, and 0.3% by mass or more and 26% by mass or less of Al.
