Abstract
A process for treating the surface of a component prior to coating. The component is made from a Ni based superalloy designed for high temperature service. Both the component and the coating include the elements Al and/or Cr. The process includes depleting the outer surface of the component of any one or a combination of Al, Ti or Cr and thereafter applying the coating directly on the depleted surface. The process minimizes the formation of a brittle gamma prime phase within the interdiffusion zone during service of the component. The process can also be used to renew old damaged coatings.
