Experiments were performed in the atmosphere of purified argon in containers made of low-carbon steel. the transfer process was checed by weighing the sample's substrate and also by the methods of metallographic and X-ray microanalysis of the surface layer and cross microsections. The mass transfer was analyzed as Mn, Mo, Ni, Co, Cr - Fe in the LiCl-Li melt, Mn, Cr - Fe and Mn - Ti in the CaCl2-Ca melt, and Mo, Cr, Ni - Fe and Cu - Ni in the BaCl2-Ba melt. The direction of transfer in ionic-electronic melts was from less soluble to more soluble metals. We hypothesize that d-metals are transferred by their anions Me(n-) in ionic-electronic melts |
