  • Beschreibung: <jats:sec><jats:label /><jats:p>The effect of Ti<jats:sub>3</jats:sub>SiC<jats:sub>2</jats:sub> coatings on the interfacial properties of SiC‐fiber reinforced FeSiCr/SiC‐filled polymethylsilsesquioxane‐derived ceramics was investigated. An electrophoretically deposited Ti<jats:sub>3</jats:sub>SiC<jats:sub>2</jats:sub> coating was prepared on the fiber/matrix interface. Interfacial parameters such as frictional sliding stress and fracture energy were derived from fiber push‐out tests and correlated to the thickness of the Ti<jats:sub>3</jats:sub>SiC<jats:sub>2</jats:sub> layer. Compared to uncoated fibers, the Ti<jats:sub>3</jats:sub>SiC<jats:sub>2</jats:sub> interlayer gives rise for a pronounced enhance of interface shear strength, coefficient of friction, and sliding strength but a reduced fracture energy. With increasing Ti<jats:sub>3</jats:sub>SiC<jats:sub>2</jats:sub> coating thickness, thermal mismatch‐induced residual compressive stresses at the fiber/matrix interface tend to decrease significantly.</jats:p></jats:sec>
