Paper Title:
Corrosion Behavior Improvements of High Active Aluminum Alloy Anode in Alkaline Solution by Adding Inhibitors
  Abstract

The Na2SnO3 and H-N-R inhibitors effects on the high active aluminum alloy in alkaline solution (805mol/LNaOH) have been systematically studied by hydrogen collection and electrochemical measurement in the present investigation. The results showed that the hydrogen evolution rate was low at the value of 0.404 mL/ (min·cm2) in alkaline solution with 0.01mol/L Na2SnO3, but the electrode potential was only -1.515Vvs.SCE and it moved to the positive direction seriously; When adding 10wtH-N-R and 0.01mol/LNa2SnO3 into the alkaline solution simultaneously, the aluminum alloy anode had a lower hydrogen evolution rate of 0.342mL/ (min·cm2) and a more negative electrode potential of -1.591Vvs.SCE. The electrochemical performance of aluminum alloy anode has been improved greatly by the cooperation of H-N-R and Na2SnO3.
