Özet

Fitting corrosion of aluminum alloy 7075 in 0.05 M NaCl solution at pH values of 4, 5, 7 and 8 were examined by potentiostatic method. It was found that addition of 10(-2) M hydroxy carboxylic acids or amino acids to NaCl solutions cause shifting of E-pit values to noble directions. Amino acids are more effective in shifting E-pit values to noble directions in acidic solutions while hydroxy carboxylic acids are effective in shifting E-pit values to noble directions in neutral or basic solutions.
