摘要： A method for forming integral extensions on the end (4) of directionally oriented, superalloy articles (2), such as airfoil blading members or other components used in gas turbine or other turbine engines. An extension is formed directly on an article by casting a compatible molten material (26) from a reservoir (80) into a ceramic mold (16) that is attached on an end of the article, followed by cooling of the end under controlled conditions sufficient to cause an integral extension to solidify on the article. A ceramic mold is utilized over the end of the article, with a mold cavity that generally defines the shape of the extension to be formed. The mold may be formed in situ on the mandrel, or preformed and attached to the subject article over the madrel. Extensions formed by the method of this invention have a microstructure that is continuous and compatible with that of the article. Such microstructures may include epitaxial growth of the extension from the microstructure of the article. The method establishes a temperature gradient within the article during solidification that may be further controlled by auxiliary heating and/or cooling of the article and/or extension during the practice of the method.

摘要： A method for forming integral extensions on the end of directionally oriented, superalloy articles 100, such as airfoil blading members for use in turbine engines is described in which an extension is formed directly on the end of an article by dipping 300 the end into a molten bath of an alloy 200, followed by withdrawal 400 of the end at a rate sufficient to form the extension. Extensions formed by the method of this invention have a microstructure that is continuous and compatible with that of the article. Such microstructures may include epitaxial growth of the extension onto the microstructure of the article. The method establishes a temperature gradient within the article that may be controlled by heating and/or cooling, 600, 700 or 800, the article and/or extension during the practice of the method. A sacrificial material or a barrier material may be secured to the end of the extension prior to the step of dipping.

摘要： A method includes applying an infiltration coating on a thermal barrier coating of an article. The infiltration coating infiltrates at least some pores of the thermal barrier coating. The infiltration coating decomposes within the at least some pores of the thermal barrier coating to coat a portion of the at least some pores of the thermal barrier coating. The infiltration coating reduces a porosity of the thermal barrier coating. The method also includes applying a reactive phase spray formulation coating on the thermal barrier coating. The reactive phase spray formulation coating reacts with dust deposits on the thermal barrier coating.

摘要： An atomizing spray nozzle device includes an atomizing zone housing that receives different phases of materials used to form a coating. The atomizing zone housing mixes the different phases of the materials into a two-phase mixture of ceramic-liquid droplets in a carrier gas. The device also includes a plenum housing fluidly coupled with the atomizing housing and extending from the atomizing housing to a delivery end. The plenum housing includes an interior plenum that receives the two-phase mixture of ceramic-liquid droplets in the carrier gas from the atomizing zone housing. The device also includes one or more delivery nozzles fluidly coupled with the plenum chamber. The delivery nozzles provide outlets from which the two-phase mixture of ceramic-liquid droplets in the carrier gas is delivered onto one or more surfaces of a target object as the coating on the target object.

摘要： The disclosure relates generally to mold compositions and methods of molding and the articles so molded. More specifically, the disclosure relates to silicon carbide-containing mold compositions, silicon carbide-containing intrinsic facecoat compositions, and methods for casting titanium-containing articles, and the titanium-containing articles so molded. A slurry containing silicon carbide and calcium aluminate is introduced in a mold cavity that contains a fugitive pattern. The slurry is cured in the mold, sintered and used for casting a titanium turbine blade.

摘要： An analysis controller determines multi-dimensional characteristics of one or more corrosion pits in equipment. These characteristics can include depths, widths, and/or aspect ratios of the corrosion pits. The controller also determines one or more stresses on the equipment based on the characteristics of the corrosion that are determined. The analysis controller also generates a control signal to implement one or more remedial actions to one or more of remove the one or more corrosion pits, repair the equipment, or restrict operation of the equipment based on the one or more stresses that are determined.

摘要： Methods and systems for in situ cleaning of internal cooling circuits of a turbine engine with detergent that provide cleaning a turbine engine that includes circumferentially arranged internal impingement cooling circuits that each include a baffle plate configured to air cool a respective surface or component of the turbine engine. Detergent is introduced through the outer wall and proximate to a back side of a baffle plate such that the detergent passes through at least aperture in the baffle plate and acts at least upon the surface or component that the baffle plate is configured to cool. The detergent may also act on the front side of the baffle plate that is proximate to the surface or component.
