  • Publication number: 20220228254
    Abstract: A vapor deposition device for forming a ceramic coating on a substrate, the device including a coating chamber, loading chambers, substrate support mechanisms, horizontal moving mechanisms, and reversing mechanisms, and configured as follows. The coating chamber and each loading chambers are connected individually to a vacuumizer and are connected to each other at their openings. In the coating chamber, an electron gun is provided that emits an electron beam with which the held ceramic raw material is irradiated. Each of the substrate support mechanisms includes left and right partition walls, a left substrate support plate on the left side of the left partition wall, and a right substrate support plate on the right side of the right partition wall. Each of the substrate support plates has multiple substrate mounting portions for mounting substrates thereon.

  • Patent number: 9175369
    Abstract: A Ni-based superalloy component includes a bond coat layer having a chemical composition not allowing interdiffusion to occur on a Ni-base superalloy substrate, and by allowing the bond coat layer to have Pt and/or Ir content equal to or higher than 0.2% but not exceeding 15% by mass, generation of an SRZ, which occurs at an interface between the Ni-base superalloy substrate and the bond coat layer in a high-temperature oxidizing atmosphere, can be suppressed, and at the same time adhesion at the interface between a ceramic thermal barrier coat layer and the bond coat layer is improved. Thus, a long-life Ni-based superalloy component with suppressed elemental interdiffusion between the Ni-base superalloy substrate and the bond coat layer even at temperatures exceeding 1100° C. is provided.

  • Publication number: 20080199711
    Abstract: A heat resistant member includes a metal or ceramic substrate and a thermal-barrier coating layer disposed on the substrate. The thermal-barrier coating layer includes a metal layer functioning as a bonding layer and one or more ceramic layers disposed on the metal layer. At least one of the ceramic layers is mainly composed of a hafnium oxide-based ceramic layer containing 85% or more of hafnium oxide. Due to the above structure, there can be provided a heat resistant member with high heat resistance and durability which has a thermal-barrier coating layer with stable thermal conductivity at elevated temperatures, namely, not less than 1,200° C., and resistance to cracking and delamination due to sintering.

  • Patent number: 6398503
    Abstract: A high temperature component such a gas turbine high temperature component, for example, constituting movable or stationary blade portion, thereby comprises a base material and a thermal barrier coating coated on a surface of the base material. The thermal barrier coating has a thermal barrier characteristic controlled in accordance with an environment to which a high temperature component is exposed so as to make substantially uniform a surface temperature of the base material. The thermal barrier coating comprises a thermal barrier ceramic layer having a thermal barrier characteristic capable of being controlled by varying a thickness thereof at portions of the thermal barrier ceramic layer.
