Abstract: The invention refers to a method for producing means with thermal resist for applying at a surface of a heat exposed component. The method includes providing at least one mixture of at least two different inorganic powder materials: with different chemical composition and thermal expansion coefficient, where at least one of the powder materials experiences volume changes due to crystallographic phase change at a given temperature, and/or\where at least one of the two powder materials experiences volume changes due to chemical composition change, forming the at least one mixture into a green body shape, sintering the green body to obtain a ceramic body and cooling the ceramic body and causing micro-cracking during heating and or/sintering and/or cooling to obtain the means with thermal resist. The forming is performed such that a first mixture forming a first layer onto which a second mixture is applied forming a second layer differs in porosity from that first layer to obtain a layered green body.

Abstract: The invention refers to a method for fixing a heat resistant component on a surface of a heat exposed component, by brazing of at least a part of a surface of the heat resistant component limited by a peripheral boundary edge on the surface of the heat exposed component using a molten solder. A first alternative includes: metallizing the surface of the heat resistant component at least with the exception of an edge area comprising the peripheral boundary edge; and brazing said metallized surface to the surface of the heat exposed component, wherein at least the surface of the heat resistant component consists of a ceramic material which has a physico-chemical property concerning wettability such that the ceramic material is not wettable by the molten solder, and/or a metal or a metal alloy is used for metallizing which has a physico-chemical property concerning wettability such that the metallizing is wettable by the molten solder.
