Effect of Chloride Ions on the Corrosion Behavior of Al Zn Alloy in NaOH Solution at Four Different Temperatures

This research involves study effect of chloride ions in concentration range (0.01 0.50 mol.dm-3) on the corrosion behavior of Al-Zn alloy in basic media of 1x10-3 mol.dm-3 NaOH at pH=11 and four different temperatures in the range (298-313 K). Cathodic and anodic Tafel slopes (bc &ba) and trans...
