Abstract

The influence of alloying on the mechanical and corrosion properties of casting eutectic (a-Al + Mg₂Ge) aluminum alloys based on the Al–Mg–Ge ternary system has been stu­died. Corrosion dissolution of these alloys in 3% NaCl solution is studied by electrochemi­cal (voltammetric, chronopotentiometric) and gravimetric methods. It is shown that accor­ding to the scale of corrosion resistance these alloys are stable or very stable, and the com­bination of corrosion and strength properties can compete with industrial casting alumi­num alloys
