ABSTRACT:
A heat insulation material based on ceramic material includes a top layer containing BaZrO3and Y2O3doped ZrO2. A heat insulation material preferably consists of at least one adhesion promotion layer, at least one intermediate layer arranged thereon and a top layer arranged thereon, with the adhesion promotion layer consisting of MeCrAlY, where Me is nickel and/or cobalt, the intermediate layer consists of Y2O3doped ZrO2and the top layer consists of 15 to 25% by weight BaZrO3and 75 to 85% by weight Y2O3doped ZrO2. A method of coating a substrate with a heat insulation material includes the step of applying an aforesaid top layer to an optionally coated substrate by a thermal spray method or an electron beam method, in particular an EB-PVD method.
