Structure and electrochemical property of ball-milled Ti0.26Zr0.07Mn0.1Ni0.33V0.24 alloy with 3 mass% B

The electrochemical properties of the ball-milled Ti0.26Zr0.07V0.24Mn0.1Ni0.33-3 mass% alloy electrode are studied. The results of electrochemical impedance spectroscopy show that the exchange current density I0 increases from 116 mA g−1 (t = 20 min) to 138 mA g−1 (t = 90 min), which explains why the HRD of the alloy electrode increases with increasing ball-milling time.113
