| Abstract: | The corrosion of industrial pure aluminium in 1.0 mol.dm-3hydrochloride acid is investigated in the absence and presence of various amines,both by weight loss and electrochemistry.To begin with,the inhibition efficiency is found to follow the order: Hexamethylenetetramine>Diethylamine>n-Butylamine. With the increasing of the dipping time, the inhibition efficiency decreases gradually. The three amines, as the mixed inhibitors, has a great effect on the progress of cathodal and anodic corrosion of Al and can form a film by the adsorption on the surface of Al to protect Al from corrosion. |
