ABSTRACT:
The effect of salicylic acid in conjunction with calcium acetate on the corrosion of aluminium in sodium hydroxide (1.0N) solution has been investigated using Polarisation Measurements, Open Circuit Potential Measurements, Gasometric Measurements and Weight Loss Studies. The inhibition efficiency values determined by techniques, shows close agreement. The combination of salicylic acid and calcium acetate was found to show synergistic inhibition effect. The results collectively are in good agreement and show clearly that salicylic acid in conjunction with calcium acetate is a good corrosion inhibitor for aluminium under the conditions studied.
KEYWORDS:
Salicylic acid in conjunction with calcium acetate, Sodium hydroxide solution, aluminum and corrosion inhibition.
