    Abstract: The invention relates to a method for the production of a thin dense ceramic layer on a substrate by means of atmospheric plasma spraying, whereby the following steps are carried out: a) the substrate is pre-heated to a temperature corresponding to at least a quarter of the melting point of the ceramic for application in Kelvin, b) a ceramic powder or a ceramic powder mixture with d50-values of less than 50 gm is used as spray adjunct, c) particle speeds at incidence on the substrate of more than 200 m/s are set, d) particle temperatures are set such that on incidence on the substrate surface the particles have a temperature at least 5% above the melting point of the ceramic for application in Kelvin, e) the amount of the spray adjunct and passage speed of the plasma burner are set such that on a single pass of the substrate a layer thickness of less than 100 ?m is achieved, f) a thin and also gas-tight layer is generated on the substrate with a single pass of the substrate which has a leakage rate of less than 10−1 mbar L/(cm2 s).

    Abstract: A coating system for Si-containing materials, particularly Si-based composites used to produce articles exposed to high temperatures. The coating system is a compositionally-graded thermal/environmental barrier coating (T/EBC) system that includes an intermediate layer containing yttria-stabilized hafnia (YSHf) and mullite, alumina and/or an aluminosilicate, which is used in combination with an inner layer between a Si-containing substrate and the intermediate layer and a thermal-insulating top coat overlying the intermediate layer. The intermediate layer provides environmental protection to the silicon-containing substrate, and has a coefficient of thermal expansion between that of the top coat and that of the inner layer so as to serve as a transition layer therebetween. The intermediate layer is particular well suited for use in combination with an inner layer of an alkaline earth metal aluminosilicate (such as BSAS) and a top coat formed of YSZ or YSHf.

    Abstract: A method for protecting the hybrid ceramic structure from moisture attack in a high temperature combustion environment is provided. The structure includes a ceramic matrix composite (CMC) substrate (12). A thermal insulation material (14) is disposed on the substrate. A vapor resistant material (20) is applied through at least one surface of the hybrid ceramic structure while the hybrid ceramic structure is in a bisque condition that provides a degree of porosity to the hybrid ceramic structure so that the vapor resistant material is infiltrated through interstices available within a thickness of the hybrid ceramic structure.
