摘要

By characterizing electrochemical properties and oxide species on the surface layer with XPS analysis, the corrosion behavior of (TiZrNbTa)(90)Mo-10 high entropy alloy (HEA) was investigated under exposure to Ringer's solutions. The protectiveness of passive film formed on the alloy was deteriorated when the exposure solution became more acidic. Under exposure in neutral solution, passive film spontaneously formed on exposed surface consists of multiple species oxides. In comparison with constituting pure metals in the alloy, the HEA exhibits robust corrosion resistance in Ringer's solution.
