    Abstract: A multi-layered component, such as a rocket engine combustion chamber, includes NiAl or NiAl-based alloy as a structural layer on the “hot” side of the component. A second structural layer is formed of material selected from Ni-based superalloys, Co-based alloys, Fe-based alloys, Cu, and Cu-based alloys. The second material is more ductile than the NiAl and imparts increased toughness to the component. The second material is selected to enhance one or more predetermined physical properties of the component. Additional structural layers may be included with the additional material(s) being selected for their impact on physical properties of the component.

    Abstract: A nickel base single crystal compliant layer on a ceramic blade has the capability to sustain high stresses and high operating temperature. Layers of nickel and platinum bonded on a single crystal superalloy over a sputtered gold-chromium layer support the high stress levels at elevated temperature without extrusion of the soft platinum or nickel layer and without destruction of an NiO compliant surface. The compliant layers have survived stress and temperature conditions without failure to the ceramic blade and the system can be stressed/heated and unloaded/cooled repeatedly without damage to the ceramic blades. A single crystal nickel base superalloy (i.e., SC180) has high strength properties at elevated temperature. Thin layers of chromium followed by gold are e-beam evaporated on one side of a polished surface of the alloy. Pure nickel is electroplated over this e-beam gold-chromium layer. Platinum is either electroplated or plated electrolessly over the nickel layer. The structure is annealed in vacuum or inert atmosphere to allow the diffusion of gold-chromium alloy into the superalloy and permit the nickel layer and diffusion of nickel into platinum to form a multilayer structure which is metallurgically bonded. The sheet is oxidized in air to allow diffusion of the nickel layer through the platinum to come to the surface and oxidize forming nickel oxide. This nickel oxide layer acts as the load distribution layer which does not extrude and the structural integrity of the compliant layer is maintained by the high-strength single crystal superalloy.

    Abstract: A hybrid rotor, a manufacturing method thereof and a gas turbine realize reduced manufacturing cost and reduced weight of parts. An impeller part 31 as a rotor main part comprises a bore portion 32, impellers 34 provided therearound and a shaft bore 33 provided centrally of the bore portion 32. An enlarged shaft bore portion 35 is coaxially provided in the shaft bore 33. The impeller part 31 is made of Ti or Ni alloy by precision casting. A ring member 10 made of a metal base composite material is inserted into the enlarged shaft bore portion 35 and is bonded together by friction bonding or diffusion bonding to thereby strengthen the rotor. The rotor main part is manufactured by precision casting without need of machining. The ring member 10 is separately manufactured from the impeller part 11. By strengthening the rotor, the bore portion 32 can be made thin. Thus, manufacturing cost is remarkably reduced and weight of the rotor is also reduced.
