Disruption and sputtering erosions on SiC doped CFC

This paper describes the disruption and sputtering erosions on newly developed SiC doped carbon fiber reinforced composite (CFC). Disruption experiments were performed under heat fluxes of 1000-2000 MW/m2 with pulse length of 2-4 ms in the temperature range from RT to 1000 C at the JEBIS facility. Sputtering experiments were performed under the deuterium particle flux of 1-2 x 1020 m2/s with energy of 50-100 eV in the temperature range from 200 C to 600 C at the SLEIS facility. As a result, it is clear that the sputtering yield from 200 C to 450 C is about 0.09 and gradually decreases to 0.067 with increasing sample temperature and that the disruption erosion of SiC doped CFC was about double that of the non-doped CFC and the erosion was mainly caused by the loss of the matrix part.
