Development of new multilayer coatings with sol/gel derived mullite and alumina coatings

Most of the sol/gel coating procedures enable only layer thickness of some nanometers per coating step. A method was developed within HITHEX, which offers the possibility to increase the coating thickness per step up to 500 micrometers. Such a technology is of industrial interest. Coatings with glass sealing layers can be realized in a one step or two-step procedure saving costs and time.

Further improvements of gas tightness and density of the layers are necessary. It is expected that these problems can be solved by an optimisation of the sintering post-treatments.
