Abstract
A method for producing a component having a base body made of a carbon fiber reinforced ceramic and a protective layer which is applied on the base body includes the following steps: providing the base body: applying a first layer on the base body, the first layer comprising a slip with reactive carbon; applying a second layer on the first layer, the second layer comprising a slip with silicon. The application of the layers can be carried out by painting, brushing, filling or dipping techniques, or by fully automatable spraying devices. Finally, the silicon of the second layer is liquefied in a thermal treatment, so that the liquid silicon penetrates into the first layer and forms with the reactive carbon a reaction protective layer composed of a silicon carbide compound.
