A new corrosion inhibitor for protection of low carbon steel in HCl solution

Abstract

The effect of (E)-N-((E)-3-phenylallylidene)-2-(phenylthio)aniline (2-PTA) on the corrosion of low carbon steel (LCS) in hydrochloric acid solution was investigated with electrochemical techniques for a wide enough temperature range. The results revealed that 2-PTA inhibits the corrosion of LCS by adsorbing to a great extent, even at high temperatures. The potential and time dependent stability tests of 2-PTA film verified that 2-PTA is an effective inhibitor for the acid corrosion of LCS. (C) 2015 Elsevier Ltd. All rights reserved.
