Abstract
Methods for producing a high temperature oxidation and hot corrosion resistant MCrAlX coating on a superalloy substrate include applying an M-metal, chromium, and aluminum or an aluminum alloy comprising a reactive element to at least one surface of the superalloy component by electroplating at electroplating conditions below 100° C. in a plating bath thereby forming a plated component and heat treating the plated component.
