摘要: The microstructure and electrochemical behavior of the Pd42.5Cu30Ni7.5P20 as-quenched bulk metallic glass its crystallized alloys after heat-treatment at 623 723K were investigated. results revealed that spontaneously passivated in 0.144M NaCl Hanks’ solution with a low passive current density wide region. transpassive potential fully alloy heat-treated higher temperature was lower than those partially alloy. difference glass, responsible for their different potentials. wider region is attributed to presence HCO3 ¹ , HPO4 2¹ ,S O4 H2PO4 ions solution, which act as corrosive inhibitors.
