Abstract (en)

The heat insulation layer (7) is used in one component, e.g. a valve housing (34) of a steam turbine, which is next to a second component, e.g. a housing cover (37), to adjust, esp. even out, differing deformation behavior of the components, esp. between room and operational temperatures, to reduce radial and/or axial tolerances. The first component is subject to e heat differential of at least 200[deg]C. The heat insulation layer is used for a steam inlet section of a turbine, which is next to a blade section, a turbine housing, a valve housing unit (31), a turbine blade, or for a component consisting of a main material, e.g. iron/nickel/cobalt alloy. The heat insulation layer consists at least partially, pref. completely, of zirconium oxide (Zr02), or titanium oxide (Ti02). An intermediate protection layer below the heat insulation is a MCrAlX layer, with M being an element from the group nickel, cobalt, and esp. iron, and X being yttrium and/or silicon and/or at least one of the rare earth.
