本文报道了一种以电沉积二氧化硅(E-SiO_2)膜为预处理层的新型碳钢涂装系统。电沉积是基于负电位对正硅酸乙酯的溶胶-凝胶过程(水解和缩合反应)的基本催化作用。获得的高度多孔的E-SiO_2层确保了与面层的良好附着力。建立在E-SiO_2预处理层上的涂装体系，其耐蚀性能优于传统的磷化工艺。相信这种环保、低成本的预处理层可用于制备各种结构金属基材的高耐蚀涂装体系。
The present work reports a novel painting system for mild steels using electrodeposited silica (E-SiO2) film as the pretreatment layer. The electrodeposition is based on basic catalysis of sol–gel processes (hydrolysis and condensation reactions) of tetraethoxysilane by applying a negative potential. The highly porous E-SiO2layer obtained ensures good adhesion to the topcoat. The painting system constructed on E-SiO2pretreatment layer is superior in its corrosion performance to traditional phosphating process. It is believed that such environmentally friendly and low-cost pretreatment layer can be used to fabricate highly corrosion resistant painting system for a variety of structural metal substrates.
