Abstract

Thermal release of H and D implanted into WC layers graphite with 5 keV H-2(+) and 5 keV D-2(+) ions has been measured by means of the elastic recoildetection technique. It has been found that the thermal release on isochronal annealing taker place in three stages: the two stages at the lower temperature take place from the two trapping rites to the WC crystallites, and the last stage at the higher temperature from graphite phase segregated in grain boundaries of the WC layers. The isothermal release from the graphitephase has been measured at different temperatures at 350, 450, and 550 degreesC, for H and 450, 550 and 650 degreesC for D, respectively. The isothermal release data have been analyzed by using the mass balance equations andthe rate constants involved have been determined by fitting their solutionto the experimental data. The thermal desorption spectrum has been theoretically calculated from the solution of the mass balance equations. It has been also found that the calculated thermal desorption spectrum agrees excellently well with the experimental one obtained by Wang et al. in IPP Garching. (C) 2001 Elsevier Science B.V.
