Electrotransfer in Liquid Binary Aluminum Alloys

Abstract

The mobility of ions in a liquid binary metal system based on aluminum is calculated for the first time in a wide range of concentrations, based on studies of its resistivity and self-diffusion coefficient. It is established that in an Al–Cu system, the ions of aluminum move to the anode, while Al–Mg, Al–Sn, and Al–Sb move to the cathode; i.e., there is inversion of the electrotransfer of aluminum ions. When the concentration of a component is reduced, the mobility of its ions is increased by the module.
