    摘要: A ceramic thermal barrier coating (TBC) (18) having first and second layers (20, 22), the second layer (22) having a lower thermal conductivity than the first layer for a given density. The second layer may be formed of a material with anisotropic crystal lattice structure. Voids (24) in at least the first layer (20) make the first layer less dense than the second layer. Grooves (28) are formed in the TBC (18) for thermal strain relief. The grooves may align with fluid streamlines over the TBC. Multiple layers (84, 86, 88) may have respective sets of grooves (90), Preferred failure planes parallel to the coating surface (30) may be formed at different depths (A1, A2, A3) in the thickness of the TBC to stimulate generation of a fresh surface when a portion of the coating fails by spalling. A dense top layer (92) may provide environmental and erosion resistance.

    摘要: A thermally protective coating (21), such as may be used over a nickel-based superalloy substrate (24). The protective coating (21) includes a CoNiCrAlY or a NiCoCrAlY material and addition of given amounts of one or more secondary elements. The secondary element(s) facilitate and/or join in one or more precipitation mechanisms (γ′, B2) that retain an aluminum reservoir in the protective coating (21), reducing aluminum diffusion into the substrate (24). This aluminum reservoir maintains a protective alumina scale (38) on the coating (21), thus improving coating life and allowing higher operating temperatures.

    摘要: A thermal barrier coating (TBC) system (450) capable of self-healing has a substrate (420), a metal-based advanced bond coat (435) overlying the substrate and a ceramic top coat (440) overlying the bond coat. The bond coat (435) comprises ceramic oxide precursor materials capable of forming a non-alumina ceramic oxide composition when exposed to a thermally conditioning oxidizing environment. Embodiments of such bond coat (435) comprise rare earth elements in a range of 1-20 weight percent, and Hf in a range of about 5 to 30 weight percent or Zr in a range of about 2 to 20 weight percent. Examples of self-healing TBC systems (400, 402, 404) are provided using such bond coat (435) or its advanced bond coat chemistries in combination with conventional bond coats (433, 437) or conventional bond coat chemistries.

    摘要: A gas turbine component (49) may be instrumented to provide a plurality of signals indicative of thermal measurements in a high temperature combustion environment of the gas turbine. A thermocouple arrangement may include a first thermocouple leg (50) disposed within a thickness of the component. At least two or more thermocouple legs (52, 53, 54) is each electrically connected to the first leg to form individual thermocouple junctions (56, 57, 58, 59) along the first leg for conversion of respective thermal gradients to respective electrical signals, such as electromotive force (emf) based voltages. The thermocouple arrangement may be used in combination with a thermographic system (70) to calculate heat flux over a region of the turbine component.

    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.
