摘要: The effect of pass deformation in rolling processes on the microstructure, corrosion resistance and electrochemical activity Al-Mg-Bi-Sn-Ga-In alloy anodes operated an alkaline solution (85 °C, 5 mol·L−1 NaOH with addition NaSnO3) current density 800 mA·cm−2 was investigated. To analyze microstructure aluminum anodes, we used scanning electron microscope, transmission microscope backscatter diffraction techniques. We also hydrogen evolution method testing techniques to investigate behavior anodes. results showed that uniform microstructures homogeneous distribution fine active segregated phases as well excellent performance were achieved by dynamic recrystallization under 40%. found (under 40%) had lowest rate (0.092 mL·min−1·cm−2) most negative electrode potential (−1.585 V).
