In the previous payers (Light metals No. 8, 1953-8), one of the authors, Harimoto reported the following current of Al-Mg alloy (52S). We researched on the electrode-potential of this alloy in this paper, after heat treatments which were heated at 100°C, 200°C, 300°C, 350°C, 400°C, 450°C and 500°C. These alloys dipped in the electrolysis of 3%NaCl, 0.1%HCl and 0.5%H2SO4 and then the measured the electrode potential by the Valve Voltmeter.
Conclusion:
1. The effect of the Heat treatments. The electrode potential indicated the low value in the case of the temperatures of the heat treatment are 100°C to 200°C.
2. The effect of the oxide film. The oxide film is thicker, the electrode potential is lower.
