    • A method is provided for enhancing corrosion resistance of a metal surface that includes the step of forming a sol-gel coating in which nanostructured zinc phosphate (Zn3(PO4)2) and zinc oxide (ZnO) phases are present in the mixture. The method may include the steps of mixing an organosilane, organometallic, organic acid, water, and alcohol and allowing the components of the mixture to partially hydrolyze, followed by adding at least one component having zinc functionality and at least one component having phosphate functionality to the partially hydrolyzed mixture, wherein the zinc component and phosphate component are added in a molar ratio of from about 1.5:1 to about 5:1 (Zn:PO4). The resulting mixture can be applied as a coating to a metal surface to improve the corrosion resistance of the metal and to enhance the adhesion of resinous materials to the metal surface.
    • 提供一种用于提高金属表面的耐腐蚀性的方法,包括形成溶胶 - 凝胶涂层的步骤,其中纳米结构化磷酸锌(Zn 3(PO 4)2)和氧化锌(ZnO)相存在于混合物中。 该方法可以包括以下步骤:将有机硅烷,有机金属,有机酸,水和醇混合并使混合物的组分部分水解,然后将至少一种具有锌官能团的组分和至少一种具有磷酸酯官能团的组分加入到 部分水解的混合物,其中以约1.5:1至约5:1(Zn:PO4)的摩尔比加入锌组分和磷酸盐组分。 所得到的混合物可以作为涂层施加到金属表面以改善金属的耐腐蚀性并增强树脂材料对金属表面的粘合性。
