Properties and Characterization on a Novel Aqueous Inhibitor for Inhibiting Alloy Steel Corrosion in Chloride Solution
Publication: Journal of Materials in Civil Engineering
Volume 29, Issue 9
Abstract
A novel aqueous penetrating corrosion inhibitor marked PCI-2016 was prepared by using multicompound and chelate-induced techniques for this paper. Adsorption and inhibition behaviors of PCI-2016 in a chloride solution had been investigated. Test results indicated that the PCI-2016 had an excellent inhibition ability and an identified curative effect on the corrosive steel in the chloride solution. Adsorption of PCI-2016 molecules on the steel surface followed the Temkin adsorption isotherm. The scanning electron microscope (SEM), the energy dispersive spectrometer (EDS), and the atomic force microscope (AFM) images showed many small global or columnar substances had accumulated on the steel surface and the elements of N and Zn in corrosion inhibitors were detected on the steel surface. The X-ray photoelectron spectroscopy (XPS) measurements supported the inhibitor particles that were absorbed on the steel surface by chemisorption and a dense film was formed to inhibit the steel corrosion. Mechanism studies indicated that a stable chelate formed between the iron and N-containing polycarboxylate ligands might be responsible for the high inhibiting efficiency of the inhibitor in the chloride solution.
