Effects of Deuterium Concentration on Deuterium Desorption Temperature Range from Ni - In Composites

Abstract

Spectra thermal desorption deuterium from the samples of system Ni-In preliminary implanted by var-ious doses of deuterium ions at Т~100 K. On the basis of these spectra are studied dependences of change are constructed. It is shown that the structure of spectrum, thermal desorption deuterium is function doses. On satura-tion of composite Ni70In30 with deuterium through ion implantation at T ~100 K the ultimate attainable concentration of deuterium makes ~2 at.D/at.Met.The increase in deuterium concentration brings about in composite Ni70In30, in addition to the solid state solution deuterium (decomposition at temperature ~530 K), the formation of the hydride, whose temperature of decomposition in vacuum is ~350 K. Change of the component content in system Ni-In leads to essential change of a kind of a spectrum thermal desorption deuterium, shown in occurrence of additional temperature areas desorption (peaks) that testifies to formation of additional structural formations.
