Abstract
Thermal desorption behavior of boronized graphite irradiated by an ene rgetic hydrogen ion beam has been investigated. The desorption of meth ane (CH4) was observed to decrease due to boron addition. By comparing the ratios of the amount of H-2 desorption to CH4, a relative enhance ment of H-2 release was also observed. A model for hydrocarbon release from hydrogen-implanted graphite was applied to these experimental re sults. Results showed that the activation energy of detrapping decreas ed while that of precursor formation increased with increasing boron c ontent.
