  • 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.
