No-current diffusion saturation of nickel with gadolinium in the LiCl-KCl-GdCl3 melt

The kinetic characteristics of alloy formation during the diffusion saturation of nickel with gadolinium in the LiCl-KCl-GdCl 3 molten mixture are determined experimentally. The results of a chemical analysis, an electron probe microanalysis, and an X-ray phase analysis of coatings showed that intermetallic compounds, which are the Laves phase of the GdNi 2 composition, are formed during the no-current transfer in the surface layer of alloys. The coefficients of reactive diffusion and activation energy for the GdNi 2 compound are calculated.
