Erosion and thermal desorption characteristics under 3 KeV D 3 irradiation were investigated for 1D-carbon fiber (CF) B 4 C composites (30 to 80 CF vol%), at surface cut normal to the CF axis. Chemical sputtering rate of 1D-CF B 4 C sintered at 2100°C was lower at the CF sections than that of pure graphite, due to solid solution of boron into the CF core. On the other hand, in the case of those at below 1800°C, suppression of chemical sputtering was not observed at the center part of the CF sections. From TDS results, it is considered that the boron diffusion depths into CF do not depend on the B 4 C volume fraction, but on the sintering temperature. |
