| مستخلص: | The electrochemical properties of Al-Zn-Ga-In-(Pb/Bi) anode alloy are studied by electrochemical test, including constant current test, polarization curve test, AC impedance test. Metallographic microscope is used to observe the microstructure of the alloy . energy spectrum technical is used to analyze the second phase elements. The results showed that the adding of element Pb or Bi both can attain more negative open-circuit potential; the adding of Bi makes the working potential shift positively, and reduces the current efficiency; 2% Pb content can attain more negative working potential, and current efficiency are increased slightly; the series anode the morphology of dissolution relatively uniformly in 3% NaCl solution; anodic polarization are all relatively smaller than cathodic polarization, and they have good anodic polarization properties. The overall electrochemical properties of Al-3Zn-0.015Ga-0.025In-2Pb alloy are the best in these five aluminum alloy anode. |
