    摘要： The invention relates to a gas turbine engine comprising at least one compressor (11, 13, 14), at least one combustion chamber (15), at least one turbine (16, 17, 18), and an exhaust gas heat exchanger (23) which is used for recirculating waste heat of the exhaust gas into compressed combustion air before said compressed air is fed into a combustion chamber (15). According to the invention, the exhaust gas heat exchanger (23) is used as a support for catalysts for catalytically aftertreating the exhaust gas in order to reduce emissions, particularly NOx emissions, from the gas turbine engine.

    摘要： A gas turbine engine nozzle segment (10) and process for producing such a nozzle segment (10) to exhibit improved durability and aerodynamic performance. The process produces a nozzle segment (10) having at least one vane (12) between and interconnecting a pair of platforms (14,16). The nozzle segment (10) is cast from a gamma prime-strengthened nickel-base superalloy, on whose surface is thermal sprayed an environmental coating (22) formed of a MCrAlX-type coating material. The surface of the environmental coating (22) is then worked to cause the coating (22) to have a surface finish of less than 2.0 micrometers Ra. Cooling holes (26) are then drilled in the nozzle segment (10), after which an oxidation-resistant coating (24) is applied on the smoothed surface of the nozzle segment (10) so as to maintain an outermost surface on the nozzle segment (10) having surface finish of less than 2.0 micrometers Ra.

    摘要： A thermal barrier coating, or TBC, and a method for forming the TBC is described The TBC is formed of a thermal-insulating material that contains yttria-stabilized zirconia (YSZ) alloyed with at least a third oxide. The TBC is formed to also contain elemental carbon, and may potentially contain carbides and/or a carbon-containing gas that forms from the thermal decomposition of carbon. The TBC is characterized by lower density and thermal conductivity, high temperature stability and improved mechanical properties. To exhibit the desired effect, the third oxide is more particularly one that increases the lattice strain energy of the TBC microstructure as a result of having an ion size that is sufficiently different than a zirconium ion.
