Corrosion Resistance of Eutectic Al–Mg–Ge Alloys

The influence of alloying on the mechanical and corrosion properties of casting eutectic (α-Al + Mg 2 Ge) aluminum alloys based on the Al–Mg–Ge ternary system was studied. Corrosion dissolution of aluminum alloys in a 3% NaCl solution was studied by electrochemical (voltammetric, chronopotentiometri...

Description
Summary:The influence of alloying on the mechanical and corrosion properties of casting eutectic (α-Al + Mg 2 Ge) aluminum alloys based on the Al–Mg–Ge ternary system was studied. Corrosion dissolution of aluminum alloys in a 3% NaCl solution was studied by electrochemical (voltammetric, chronopotentiometric) and gravimetric methods. It was shown that according to the scale of corrosion resistance these alloys are stable or very stable, and by the combination of corrosion and strength properties can compete with industrial casting aluminum alloys.
