Method of producing a coating layer on a localized area of a superalloy
component
Abstract:
A method of producing a coating layer on a localized area of a superalloy component comprises the steps of:a) producing a coating layer element with specific functional properties;b) depositing on at least one surface of the coating layer element a uniform layer obtained from a powder mixture consisting of a powder of a nickel or cobalt superalloy and a powder of a brazing filler metal;c) brazing the coated composite coating layer element obtained from step (b) on to the localized area of the component; and,d) machine finishing the component.
