Effect of the Corrosion Inhibition Behavior of Polyaspartic Acid and Its Mixture of Zinc Ion on Carbon Steel

In this paper, the effect of the corrosion inhibition to carbon steel of polyaspartic acid and its mixture of zinc ion is discussed. It shows that the corrosion inhibition of polyaspartic acid is excellent; zinc ion can decrease the dosage of polyaspartic acid. The characteristic of mixed corrosion inhibitors shows up from the mixture of plolyaspartic acid and zinc ion.
