摘要： The present invention provides a sacrificial electrode material which consists of a single phase amorphous structure or a structure consisting of an amorphous phase and a crystalline solid solution phase and provides electrochemical corrosion protection to metallic articles exposed to an aqueous electrolytic solution. The electrode material is prepared by rapidly quenching a magnesium-based alloy material from the liquid phase or vapor phase thereof, the magnesium-based alloy material consisting of a composition represented by the general formula: Mg bal Xl a X2 b or Mg bal X1 a , wherein X1 is at least one element selected from the group consisting of Al, Zn, Ga, Ca and In; X2 is at least one element selected from the group consisting of Mm (misch metal), Y and rare earth metal elements; a and b are, in atomic percentages, 5.0 ≦ a ≦ 35.0 and 3.0 ≦ b ≦ 25.0, respectively. The magnesium-based alloy material may further contain one or more transition metal elements in their total contents not exceeding 1.0 atomic %.
