摘要

Retention behavior and chemical behavior of deuterium implanted into WC were studied by means of XPS and TDS. It was found from the TDS spectra that the deuterium desorptions consisted of four stages for WC, where the two peaks at lower temperature were attributed to the desorption of deuterium retained in the interstitial sites of WC lattice, the third one to that trapped by carbon vacancy which induced by chemical sputtering of the energetic deuterium, and the fourth one was originated from the desorption of deuterium bound to carbon as forming C-D bond. In the present study, it can be said that the deuterium retention was much less than those in other carbon materials such as graphite and SiC.
