ABSTRACT:
A method for reaction control coating includes: (a) a step of applying a reaction control material to a surface of an Ni-base superalloy before applying aluminum diffusion coating to the Ni-base superalloy, wherein the reaction control material is Co, Cr or Ru, or an alloy of which main component is selected from the group consisting of Co, Cr, and Ru; and (b) a step of applying the aluminum diffusion coating to the Ni-base superalloy.
