  • Thermal-insulating material having an essentially magnetoplumbitic crystal structure
    Patent number: 7105236
    Abstract: The subject matter of the invention is a thermal-insulating material having an essentially magnetoplumbitic crystal structure, a metal substrate having a adhesive layer and a thermal-insulating layer made of the thermal-insulating material on its surface, and a process for coating metal substrates with the thermal-insulating material.
    Type: Grant

  • Thermal-insulating material having an essentially magnetoplumbitic crystal structure
    Patent number: 7048836
    Abstract: Thermal-insulating material provided on a metal substrate by means of an EB-PVD process includes a metal having a substantially magnetoplumbitic crystal structure and having a chemical composition according to general formula: Ln3+M2+1+xQ44+A111?2xO19. The thermally-insulated metal substrate may advantageously include an adhesive layer provided between the surface of the metal substrate and the thermal-insulating layer. The process for producing the thermal-insulated metal substrate includes applying the thermal-insulating material onto a surface of the metal substrate employing an EB-PVD process.

  • 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.
