  • Ceramic heat-insulating layers with club-structure
    Patent number: 6333090
    Abstract: The present invention relates to a process for vapor-depositing zirconium dioxide on ceramic or metallic substrates, and the heat-insulating layers obtainable by such process.
    Type: Grant
    Filed: March 7, 2000
    Date of Patent: December 25, 2001
    Assignee: DLR Deutsches Zentrum fur Luft-Und Raumfahrt E.V.
    Inventors: Uwe Schulz, Claus-Jürgen Kröder, Jörg Brien, Hartmut Schurmann, Klaus Fritscher
  • Heat-insulating layers on monocrystalline and polycrystalline metal substrates having an improved crystallographic relationship between layer and substrate
    Patent number: 6127006
    Abstract: The present invention relates to a method for coating monocrystalline or polycrystalline metal substrates with a ceramic heat-insulating layer of zirconia by electron-beam vapor deposition, and to a method for coating turbine blades made of Ni-based superalloys. The method is characterized in that the metal substrate is moved during the vapor deposition in terms of a superposition of two rotational motions around horizontal axes, but in essentially perpendicular directions.

  • Ceramic heat-insulating layers with club-structure
    Patent number: 6063435
    Abstract: The present invention relates to a process for vapor-depositing zirconium dioxide on ceramic or metallic substrates, and the heat-insulating layers obtainable by such process.In particular, the invention relates to a process for vapor-depositing zirconium dioxide, optionally doped with rare-earth metal oxides or mixtures of such oxides, on ceramic or metallic substrates in a range of substrate temperatures of from 600 to 1550.degree. C. while the substrate is continuously rotated at a speed in the range of from 1 to 300 rpm, characterized in that, following the nucleation phase, the rotational speed and the temperature are adjusted to a range defined by the equations: ##EQU1## where T represents the substrate temperature in .degree. K, and .omega. represents the rotational speed of the substrate in rpm, wherein the rotational speed is varied continuously or discontinuously, or alternatively in alternating senses of rotation.
