Effect of Rolling Technology on the Microstructure and Properties of High Active Aluminum Alloy Anode

Abstract:

The effect of rolling technology on the microstructure, electrochemical property and anti-corrosion property of Al-Mg-Sn-Bi-Ga-In alloy anode in alkaline solution (80°C, Na2SnO3 + 5mol/L NaOH) has been analyzed according to the chronopotentiometry (E-T curves), hydrogen collection tests and modern microstructure analysis. The results show that when controlling the pass deformation at 40%, with the increase of rolling temperature, both electrochemical activity and anti-corrosion property of Al anode increase first and then decrease. When the rolling temperature is 420°C, the aluminum alloy anode has the most negative electrode potential of about -1.521V (vs.Hg/HgO) and the lowest hydrogen evolution rate of 0.1716mL/ (min•cm2). The optimum comprehensive performance of Al alloy anode has been obtained.
