    摘要: The invention relates to a material, in particular for a thermal insulation layer, with increased thermal stability, a low heat conductivity and a large thermal coefficient of expansion. According to the invention, said material comprises lanthanides, in particular the elements La, Ce, Nd, Yb, Lu, Er or Tm, which preferably occur as a mixture in a Perovskite structure. Said thermal insulation layer is particularly suitable for replacing thermal insulation layers comprising yttrium stabilized zirconium oxides (YSZ) as the thermal stability thereof is given as well over 1200° C.

    摘要: The invention relates to a method for producing a tight crystalline mullite layer on a metallic and/or ceramic substrate by using the plasma spraying technique. To this end, a sol containing mullite precursors with a proportion of 2 to 25% by weight with regard to the oxides (3 Al2O3/2 SiO2) is used as a spraying additive. This method is carried out under atmospheric conditions, and the sol is injected with a focussed jet and with an overpressure of at least one I bar into the plasma flame. An additional compacting of the layer can be advantageously effected by repeatedly passing over the layer with the plasma flame. The method is particularly suited for applying a gas-tight crystalline mullite layer to a steel substrate.

    摘要: Disclosed is a method for producing a coating system on a component, wherein at least one coating is deposited on the component by way of atmospheric plasma spraying (APS) and at least one further coating is deposited by way of suspension plasma spraying (SPS). The coatings are particularly advantageously deposited in the sequence of APS+SPS or APS+SPS+APS or APS+SPS+erosion coating. These sequences of coatings applied in this way usually have an effect providing a first porous coating and a second porous coating disposed thereon, wherein the porosity of the second coating is greater than that of the first coating, and wherein the reflectivity is greater than that of the first coating. The increased reflectivity of the coating, particularly in the visible (VIS) and the near infrared (NIR) wavelength ranges, advantageously causes a lower thermal load for the substrate material because a smaller proportion of thermal radiation penetrates the ceramic thermal barrier coating, resulting in lower heating of the substrate (component).

    摘要: A method produces thermal barrier coatings that adhere to components even at high temperatures and temperatures that change frequently. A gas-tight glass-metal composite coating is applied to the component and annealed. The corroded part of the gas-tight coating is then removed, and a second, porous coating is applied. The second coating can comprise a ceramic, in particular yttrium-stabilized zirconium oxide. A thermal barrier coating is provided that is a composite made of a gas-tight glass-metal composite coating and another porous coating disposed thereover. Because the boundary volume of the composite coating is partly crystallized to the other coating, superior adhesion within the composite is achieved. Thus, it is in particular possible to produce a composite made of silicate glass-metal composite coatings and yttrium-stabilized zirconium oxide that are temperature-stable for extended periods of time. Such a composite is particularly advantageous for use as a thermal barrier coating because it combines good protection against oxidation with low heat conductivity and susceptibility to aging.
