| Popis: | This chapter considers the evolution of the structure of the nickel surface layer under the action of deuterium ions with increasing radiation dose. The kinetics of structural transformation development in the implantation steel layer was traced from deuterium thermodesorption spectra (TDS) as a function of implanted deuterium concentration. The sample structure was examined by means of transmission electron microscopy at a voltage of 100 kV. The magnetic characteristics of nickel were measured with a bar-and-yoke permeameter. It is shown that the formed structure controls the rate and temperature of desorption of the implanted deuterium ions. The concentrations of implanted deuterium were estimated with due regard for both the amount of metal atoms in the implanted layer and the amount of implanted deuterium. The estimation has shown that saturation of nickel with deuterium is attained at deuterium concentration C (at.D/at.met.) ≈ 1.0. |
