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: A stator component of a turbomachine includes at least one axially extending outer ring which serves as a frame of an inner ring composed of partial segments. The partial segments are arranged on one another such that, on the rotor side, to form a coherent circular circumferential surface in relation to the rotational movement of rotor blades. The individual partial segment is composed of a material of uniform construction or, at least in a radial direction, of multiple partial bodies constructed from different materials, such as for example ceramic, wherein a partial segment thus formed exhibits predetermined stress and/or expansion behavior as a function of the load ranges of the turbomachine.
