  • Layer systems consist of a substrate and at least a layer lying on the substrate. Substrates need for example, in gas turbine construction from too high temperatures and / or corrosive attacks are protected. For example by making a sheet on the substrate is applied with a honeycomb structure, the honeycomb are filled with a ceramic. The ceramics take over essentially the protective function. The sheet of the honeycomb structure serves to mechanically stabilize the ceramic. However, the mechanical connection between the ceramics and the inner surfaces of the honeycomb structure, so that the ceramics come off again and again.
