Corrosion of aluminium in aliphatic amines and its inhibition by some dyes

摘要

AbstractCorrosion rates of aluminium alloys 2S, 3S, M57S and B26S in aqueous solutions of aliphatic amines and the inhibition efficiency of some dyes on the corrosion of 3S aluminium in these amines has been studied. The corrosion rate increases with the amine concentration up to 0.1 M and then decreases. The general order of corrosivity of amines is: tertiary
