| 摘要 | Effects of a hormone biosynthetic inhibitor on corrosion resistance of copper in synthetic seawater under various conditions were evaluated via quantum chemistry calculations, weight loss, electrochemical techniques, SEM, EDS, and FTIR. Comparable results show that uniconazole acts as a mixed-type inhibitor, suppressing charge transfer process by adsorption on copper surface. Thermodynamic calculation indicates that chemisorption is in accordance with Langmuir isotherm and adsorption amount increases with immersion time. The corrosion resistance with inhibitor under alkaline conditions is better than that under acidic or neutral conditions. Good inhibition performances at different temperatures and during a long time immersion are observed. (C) 2011 Elsevier Ltd.
