Disclosed is a heat insulation layer system for metallic components, in particular for components stressed by high temperatures and/or hot gas, of a flow machine, having at least one heat insulation layer of a material comprising at least one component having at least one phase which stoichiometrically contains from 1 to 80 mol % of Mx2O3, from 0.5 to 80 mol % of MyO with Al2O3 and unavoidable impurities as balance, where Mx is selected from the elements lanthanum, neodymium, chromium or mixtures thereof and My is selected from alkaline earth metals, transition metals, rare earths or mixtures thereof, where an Al2O3 layer is present on the at least one heat insulation layer on the side facing away from the component. |
