Components for first wall applications in future nuclear fusion devices like ITER or DEMO need to fulfill special requirements. Especially transient thermal loads like Edge Localized Modes (ELMs) have a severe impact on the material damage. Tungsten coatings are being assessed for use instead of bulk tungsten. In order to quantify their material degradation, tungsten coatings on a fiber-reinforced graphite substrate were exposed to repeated short fusion relevant thermal pulses in an electron beam material test facility JUDITH 1 (Juelich Divertor Test Facility in Hot Cells).
