Abstract
Surface analysis obtained with the use of high resolution scanning electron microscopy and in situ atomic force microscopy revealed different morphology characteristics developed at the zinc surface in the presence of polyoxyethylene backbone based organic inhibitors. Fourier transform Infrared spectroscopy data show that polyoxyethylene alkyl phosphate ester acid [GAFAC RA 600] adsorbed on the zinc surface via the phosphonium ion head, while polyethylene glycol is adsorbed on the zinc surface via the alkoxide anion head. It was also established that the preferred organic inhibitor should include a linear polyoxyethylene chain. © 2003 The Electrochemical Society. All rights reserved.
