Disruption and sputtering erosions on SiC doped CFC

This paper describes the disruption and sputtering erosions on newly develo ped SiC doped Carbon fiber reinforced composite (CFC). Disruption experimen ts were performed under heat fluxes of 1000-2000 MW/m(2) with pulse length of 2-4 ms in the temperature range from RT to 1000 degrees C at the JEBIS f acility. Sputtering experiments were performed under the deuterium particle flux of 1-2 x 10(20) m(2)/s with energy of 50-100 eV in the temperature ra nge from 200 degrees C to 600 degrees C at the SLEIS facility. As a result, it is clear that the sputtering yield from 200 degrees C to 450 degrees C is about 0.09 and gradually decreases to 0.067 with increasing sample tempe rature and that the disruption erosion of SiC doped CFC was about double th at of the non-doped CFC and the erosion was mainly caused by the loss of th e matrix part.
