Abstract This work aims to study the effect of H2O2 in acid treatment solution on the protective properties of silane coating on mild steel. To this end, different concentrations of H2O2 up to 250 ppm were added to the sulfuric acid solution. The surface morphology, surface roughness, wettability and corrosion behavior of mild steel in the acid treatment solution were studied by SEM, GIXRD, AFM, contact angle, OCP and EIS. Then, a silane coating was applied onto the acid treated samples. It was found that H2O2 at optimal concentration (150 ppm) can improve corrosion protective properties of the silane coating.

在低碳钢上制备保护性硅烷涂层：过氧化氢在酸处理溶液中的作用

摘要 本工作旨在研究酸处理液中H2O2对硅烷涂层对低碳钢保护性能的影响。为此，将高达 250 ppm 的不同浓度的 H2O2 添加到硫酸溶液中。采用SEM、GIXRD、AFM、接触角、OCP和EIS研究了低碳钢在酸处理液中的表面形貌、表面粗糙度、润湿性和腐蚀行为。然后，将硅烷涂层施加到酸处理过的样品上。发现最佳浓度 (150 ppm) 的 H2O2 可以提高硅烷涂层的防腐蚀性能。
