Abstract (en)

Coating a nickel or cobalt base superalloy substrate, comprises: providing a supersonic gas stream having solid-phase alloy particles and having a gas stream temperature to maintain the particles below their melting temperature; and impinging the solid-phase particles in the supersonic gas stream against the substrate to deposit overlay coating. Coating a nickel or cobalt base superalloy substrate, comprises: providing a supersonic gas stream having solid-phase MCrAlX alloy particles and having a gas stream temperature to maintain the particles below their melting temperature; and impinging the solid-phase particles in the supersonic gas stream against the substrate to deposit MCrAlX overlay coating. M : Ni, Co and/or Fe; X : element other than M, Cr or Al. An independent claim is also included for a coated gas turbine engine component, comprising a nickel or cobalt base superalloy substrate and an MCrAlX overlay coating sprayed on the substrate.
