A Novel High-Entropy Alloy AlMgZnSnPbCuMnNi with Low Free Corrosion Potential

Abstract:

A novel AlMgZnSnPbCuMnNi high entropy alloy was prepared by flux melting in the atmosphere. The microstructure and the electrochemical performances of the as-prepared alloy were studied by electrochemical workstation, X-ray diffraction and scanning electron microscopy. It was found that the free corrosion potential is as low as-1.33V in the 3.5%NaCl solution in spite of the content of Al, Mg and Zn element of the high entropy alloy is far below than that of the traditional zinc or aluminum sacrificial anode material while the free corrosion current density is 2.93×10^-5 A/cm² which is close to the typical aluminum sacrificial anode material.
