摘要： The invention relates to a method for production of thermal insulation layers which adhere better to components even at high, frequently changing temperatures. A gas-tight glass-metal composite layer is applied to the component and aged. The corroded part of the gas-tight layer is then removed and a second porous layer applied which can be made from a ceramic material in particular, an yttrium-stabilised zirconium oxide. The invention further relates to a thermal insulation layer which is made up of a sandwich of a gas-tight glass-metal composite layer and a superimposed further porous layer. As a result of the boundary volumes of the composite layer with the further layer being partly crystalline the adhesion within the sandwich is markedly improved with relation to the prior art. It is thus possible to produce a sandwich of silicate glass- metal composite layers and yttrium-stabilised zirconium oxide which is stable to heat over a long period of time. Such a sandwich is particularly useful for application as thermal insulation layer due to combining good oxidation protection with a low heat conductivity and low susceptibility to aging.
