Development of a novel coating system for the oxidative and mechanical protection of carbon materials

Project description: The aim is to develop a ceramic coating system that ensures long-lasting oxidation protection of CFC materials in industrial use at high temperatures. This coating system should seal the surface of the very inhomogeneous, CFC material, have good adhesion, be resistant to thermal shock and wear, and be chemically inert to components during processing. To achieve the goals, a multicomponent system has to be found, consisting of the one hand of different ceramic fillers to meet the thermal/mechanical properties. On the other hand, a non-oxide, preceramic polymer is needed, which acts as a ceramic binder to ensure adhesion of the filler particles to each other and of the layer to the substrate, as well as enabling easy application. The extends the CFC application range in oxygen-containing atmospheres beyond 400 °C, closing a technical market gap and enabling timely cost amortization.
