Method of producing a coating layer on a localized area of a superalloy component.

摘要

The method concerns joining of a component (6) to a localised zone of a superalloy workpiece (5), and is characterised by the following steps: a) provision of a component (6) made of a metal with specific functional properties adapted to the workpiece zone in question; b) application of a brazing coating - which is obtained from a mixture of a powder of nickel or cobalt superalloy and a powder of the metal of the component (6) - to at least one surface of the component (6); c) brazing of the component to the workpiece; d) finish machining of the workpiece.
