“…In the PBS solution, although the Ti-Zr-Nb MEAs exhibited lower J corr values, Ti 25 Zr 25 Nb 15 V 15 Ta 20 HEA showed a more positive E corr (<−148 mV after stabilization) in comparison to E corr , ranging from −400 mV to −600 mV vs. SCE for the MEA alloys [59]. E corr of the TiZrHfNbFe x (x = 0, 0.25, 0.5, 0.75, 1, 1.5, and 2) was also slightly more negative in the PBS solution, with relatively better corrosion resistance, which may be because the experiments were conducted at room temperature with slower ion activity [60].…”
