Abstract
Gravimetry is used to study the effect of temperature T and time τ on the specific change in the nickel sample weight Δm/s (s is the sample surface area) during no-current diffusion saturation with samarium in a LiCl-KCl-SmCl3 melt. The dependence of Δm/s on τ in the temperature range 673–873 K is obtained, and the Ni-Sm alloys synthesized on the sample surface are examined by chemical, X-ray diffraction, and electron-probe analyses. The potentials of nickel samples during saturation with samarium are measured. The measurement results support the fact that the diffusion layer consists of one structural zone, whose composition corresponds to a Laves phase.
