摘要：
The mechanism of corrosion of aluminium and the effect of polyethylene glycol (PEG) polymer as corrosion inhibitor in acidic medium has been studied using the weight loss method, potentiodynamic and galvanostatic polarization measurements. Differential pulse polarography (DPP) and differential pulse anodic stripping voltammetry have been used for the study of corrosion rates for the corrosion of aluminium in acidic medium at short time intervals. Corrosion of B-265 aluminium in 60% HNO3 solution with and without polyethylene glycol inhibitor at short time interval has been reported. The corrosion inhibition efficiency of PEG is 94% after 24 h.
