Abstract

The present paper discusses results of research concerning the process of continuous modification of the EN AC-42000 (AlSi7Mg) alloy with sodium, based on electrolysis of sodium salts, occurring directly in a melting pot with the liquid alloy. Sodium ions formed as a result of dissociation of the sodium salt and the electrolysis are “transferred” through walls of the retort made from solid electrolyte. Upon contact with the liquid alloy, as a cathode, sodium ions are transformed into atomic state, modifying the alloy. As a measure of the extent of the alloy modification impact strength, elongation A₅ and analysis of the microstructure have been obtained, which confirmed the achievement of modification of the alloy under analysis.
