    摘要: A method of locally repairing a coating (50) on a gas turbine engine nozzle guide vane (26) or a turbine blade (30,30B) comprises removing a damaged portion of the coating (50) from a portion (53) of the article. Any oxidised layer (54) is removed from the portion (53) of the surface of the article. Material is placed on the portion (53) of the article (26,30,30B) to form a patch coating (50B). The material is heated to form a patch coating (50B) on the portion (53) of the article (26,30,30B) and to bond the patch coating (50B) to the portion (53) of the article (26,30,30B) and to the coating surrounding the patch coating (50B). A high energy beam is impinged on the coating (50) and the high energy beam is moved from the periphery (60) of the patch coating (50B) to the periphery (62) of the coating (50) in a pattern (P) to uniformly heat the periphery (60) of the patch coating (50B) and the periphery (62) of the coating (50). The advantage is that a halo effect around the patch coating (50B) is obviated.

    摘要: The present method creates a relatively thin in situ brazing alloy layer upon first and second component edges which are brought together in order to create a component joint. This in situ brazing alloy layer is created by deposition of brazing elements, such as copper or nickel, from an electrical discharge cutting process electrode depletion utilized in order to cut the component edges, and then a subsequent brazing technique creates through interstitial migration between that brazing alloy layer and the underlying material substrate of the components a robust component joint wherein the in situ brazing alloy layer penetrates the respective component cut edge surface to only a limited depth such that the geometric effect is similarly limited, and the properties of the underlying component material structure are maintained.

    摘要: A method of locally repairing an aluminide coating (50) on a gas turbine engine nozzle guide vane (26) or a turbine blade (30,30B) comprises removing a damaged portion of the aluminide coating (50) from a portion (53) of the surface of the article. Any oxidised layer (54) is removed from the portion (53) of the surface of the article. Stoichiometric amounts of nickel and aluminium are placed on the portion (53) of the surface of the article using at least one foil (57). The stoichiometric amounts of nickel and aluminium are heat treated to form an aluminide patch coating (50B) on the portion (53) of the surface of the article and to bond the aluminide patch coating (50B) to the portion (53) of the surface of the article and to the aluminide coating (50) surrounding the aluminide patch coating (50B). The advantage is that the aluminide coating (50) surrounding the aluminide patch coating (50B) is not over aluminised.
