    摘要: An article for high temperature service is presented. The article includes a substrate and a thermal barrier coating disposed on the substrate. The thermal barrier coating includes a plurality of aluminum-based particles dispersed in an inorganic binder, wherein the aluminum-based particles are substantially spaced apart from each other via the inorganic binder such that the thermal barrier coating is substantially electrically and thermally insulating. Method of making the article is also presented.

    摘要: System for selectively contacting a cleaning composition with a surface of a turbine engine component is presented. The system includes a cleaning apparatus and a manifold assembly. The cleaning apparatus includes an upper portion and a lower portion defining a cleaning chamber configured to allow selective contact between the cleaning composition and a surface of the first portion of the turbine engine component. The upper portion includes a plurality of fill holes in fluid communication with the cleaning chamber, and the lower portion includes a plurality of drain holes in fluid communication with the cleaning chamber. The manifold assembly is configured to selectively circulate the cleaning composition from a reservoir to the cleaning chamber via the plurality of fill holes, and recirculate the cleaning composition from the cleaning chamber to the reservoir via the plurality of drain holes. Methods for selectively cleaning a turbine engine component is also presented.

    摘要: The present disclosure provides methods and systems of generating flows of detergent through a turbine engine to effectuate cleaning of components thereof. The methods include introducing a foamed, acid-including detergent with a pH range of between 2 and 7 into a gas flowpath of the turbine engine. The methods also include creating a pressure differential in an aft portion of the gas flowpath with respect to a forward portion of the gas flowpath to generate a flow of the detergent therethrough. The methods further include creating a pressure differential in a forward portion of the gas flowpath with respect to an aft portion of the gas flowpath to generate a counterflow of the detergent therethrough. The flow and counterflow of the detergent through the gas flowpath interact with components of the turbine engine having foreign material thereon to at least partially remove the foreign material therefrom.

    摘要: The present disclosure relates to systems and methods useful for non-destructive evaluation (NDE) of molds and crucibles used in investment casting processes, including, without limitation, for producing aircraft engines, land-based turbine engines, and the like. According to one aspect, the present disclosure provides a system for non-destructive evaluation that includes a support, a 3D scanning device, and a computer component. According to another aspect, the present disclosure provides a method for non-destructive evaluation that includes the steps of: providing a system for non-destructive evaluation of a mold or crucible according to the present disclosure; securing a mold or crucible to the support of the system; and operating the 3D scanning device of the system in conjunction with the computer component in order to create a 3D structure difference map that indicates whether the mold or crucible falls within or outside a desired structural integrity parameter range.
