ABSTRACT
The electric field, acting on the surface of the melt, promoted the formation of ions of different atomicity. The atomicity of ions was determined from the change in the weight of the Fe-Al melt in the experiment with negative and positive polarity. The influence of temperature, amount of electricity passed, polarity and interelectrode voltage is taken into account. The atomicity of the ions of the transported element is calculated by the mass of the monoatomic one. It is determined by the amount of electricity required for its transfer and the corresponding proportion of ions. The required amount of electricity represented a fraction of the past. It is calculated as the ratio of the product of the fraction of ions in electricity and the atomic weight of an element to the sum of their values of all participants in the transfer. The sum of the products of the masses of monatomic ions by the determined number of atoms in polyatomic ions corresponded to the mass transfer in the experiment. The obtained linear equations made it possible to determine the number of atoms and the mass of ions. Their change was traced during the periods of the experiment at different polarities of the melt. With negative polarity, the elements were removed from the melt, with positive polarity, from the surface of the molybdenum electrode. The atomicity and mass of ions decreased with the removal of elements from the melt during the period of the experiment. At the beginning, ions Al7+, Fe3+, FeAl+ were removed, at the end Al+, Fe+. The transfer of elements into the melt is associated with the formation of MoAl3 and the lack of stability in the composition of the surface layer of the molybdenum electrode. At the beginning, the ions Al3+, Fe5+, FeAl+ and MoAl3+ were transferred. The rest of the time, ions were transferred without MoAl3 with a smaller difference in atomicity. The stability of the composition of the surface layer increased. The discrepancy between the calculated masses of ions of the transferred elements in helium at negative and positive polarity and those obtained in the experiment was less than a percent.
