    摘要： A metallic article adapted to be exposed to a gas during operation conditions is provided. The metallic article includes a metallic substrate, and a thermal barrier coating on the metallic substrate for restricting heat transfer from the gas to the metallic substrate. The thermal barrier coating includes a coating of a ceramic material formed by a deposition of powdered particles of said ceramic material defining a porous microstructure, wherein the porous microstructure has an average pore size ‘d’, such that d ≤ 0.001 · T p , where d is the average pore size in μm, T is an absolute temperature of the gas, and P is a pressure of gas in atmospheres

    摘要： A bracket assembly is used to mount a wireless telemetry component proximate a rotating component of a combustion turbine engine (10), wherein the wireless telemetry component includes an RF transparent ceramic cover (128). The bracket assembly comprises a first mounting bracket (125) on a surface proximate the rotating component that includes a first (138) and second (139) bracket member spaced apart from one another. The first (138) and second (139) bracket members are disposed generally perpendicular to a direction of centrifugal forces generated by the rotating component. At least one of the first (138) or second bracket (139) members is inclined toward the other bracket member and disposed at an acute angle relative to the surface (141) proximate the rotating component.

    摘要： The present invention provides near-surface cooled airfoils that can be made with near-surface cooling passages that are completely free of any leachable or otherwise sacrificial material in the recessed portion of the outer surface of the core. The turbine airfoil comprises a metallic core or substrate having an outer surface and one or a plurality of recessed portions of the outer surface; an intermediate metallic skin or foil having a back surface and a top surface, the back surface of the intermediate skin being bonded to the outer surface of the core such that the recessed portion(s) is sufficiently enclosed so as to form at least one or more near-surface cooling passages or pathways; and at least one or more metallic coatings of a high temperature-resistant metallic material deposited on a top surface of the intermediate skin.

    摘要： A wear sensor (30, 50, 60) installed on a surface area (24) of a component (20, 21) subject to wear from an opposing surface (74, 75). The sensor has a proximal portion (32A, 52A, 62A) and a distal portion (32C, 52C, 62C) relative to a wear starting position (26). An electrical circuit (40) measures an electrical characteristic such as resistance of the sensor, which changes with progressive reduction of the sensor from the proximal portion to the distal portion during a widening reduction wear of the surface from the starting position. The measuring circuit quantifies the electrical changes to derive a wear depth based on a known geometry of the wear depth per wear width. In this manner, wear depth may be measured with a surface mounted sensor.
