Abstract:
To protect a superalloy substrate from oxidation and hot corrosion, disclosed herein is a process that deposits successive layers on the substrate, a first layer of aluminum and of at least one element capable of being alloyed with sulphur, and a second layer of a material that isolates the at least one element capable of being alloyed with sulphur.
