    摘要: A method for preparing a protectively coated, apertured article to be recoated reduces the likelihood that the apertures will become constricted as a consequence of subsequent recoating. The invention, described in the context of a gas turbine engine blade (12) having transpiration cooling passages (34), includes the step of diffusing an auxiliary coating (52) into an existing coating (28) and into the exposed substrate material (26) at the periphery of the passages to form a diffusion zone (54). The blade is then subjected to a stripping agent so that the diffusion zone (54) any undiffused existing coating, and any undiffused auxiliary coating are removed. The method causes a compensatory enlargement of the mouth (44) of each passage so that excess coating that accumulates in the passage mouths during subsequent recoating does not restrict the flow capacity of the passages.

    摘要: A method for repairing a defect in a component having a first major surface and a second major surface, a thickness defined between the major surfaces, and an edge adjoining both the major surfaces is characterized by forming a slot cut entirely through the thickness of the component between the first and second major surfaces, the slot extending inward from the edge of the component towards an interior of the component to a depth from the edge sufficient to remove at least a substantial part of the defect, the slot defining an open end at the edge of the component, a closed end within the component, a width, a radius formed by the closed end, and opposing chamfered edges at the open end.

    摘要: A method for repairing a component having first and second major surfaces, a thickness between the major surfaces, and an edge, is characterized by utilizing a template to determine if the component is suitable for repair, and forming a slot cut entirely through the thickness of the component. The slot extends inward from the edge of the component, has an open end at the edge of the component, a closed end within the component, a width, a radius at the closed end, and chamfered edges at the open end. Forming the slot includes forming an initial cut with a first cutting surface from the edge of the component at least to the defect, finishing the initial cut to the width and the radius with a second cutting surface, resulting in a finished cut, and chamfering the edge of the finished cut with a third cutting surface.
