Deuterium retention in plasma-sprayed tungsten (PSW) was investigated by means of the thermodesorption technique. The material was irradiated by deuterium ions with energies of 200 eV and 3 keV per deuteron, achieving fluences in the range 1022 divide 1024 D/m2. The observed retention in PSW is four times higher than in polycrystalline tungsten (PCW). An additional high-temperature peak was found in the thermodesorption spectra of PSW (at 1050 K). The nature of the high-temperature peak and the mechanism of higher retention in PSW are discussed.
