    摘要: Process for depositing a coating for protection against oxidation and against hot corrosion on a superalloy substrate, and coating obtainedThe present invention relates to a process for depositing a coating for protection against oxidation and against hot corrosion on a metallic superalloy substrate (1), characterized by the fact that it comprises the deposition of the following successive layers on the substrate, a first layer of aluminium and of at least one element capable of being alloyed with sulphur, a second layer of a material that isolates said element capable of being alloyed with sulphur. The element capable of being alloyed with sulphur is chosen from the reactive elements: zirconium, hafnium, yttrium, silicon, and the rare earth elements: cerium, lanthanum, gadolinium.The invention also relates to the coating thus formed.
