摘要： 在镀锌钢板表面制备了γ-APT和γ-GPT复合硅烷膜.用扫描电子显微镜观察了处理前后膜层的微观形貌,用中性盐雾试验、电化学测试了耐蚀性,并测试了附着力、弯曲性能.结果表明:复合硅烷膜致密平整,中性盐雾试验72 h无腐蚀;阻抗值和极化电阻均增大证明复合硅烷膜能有效抑制腐蚀反应;划痕浸泡试验证明复合硅烷膜具有自修复性能;复合硅烷膜的附着力为一级、弯曲性能为1 T.

Abstract: A complex γ-APT and γ-GPT silane conversion coating was prepared on the galvanized steel sheet. The micro-morphology of the coating before and after passivation was observed by SEM. The corrosion resistance of the coating was tested by neutral salt spray test and electrochemistry test. The adhesion and flexibility of the coating were tested. The results showed that the surface of the complex silane conversion coating is completely consecutive and compact. The coating can endure the neutral salt spray test for 72 h. The complex silane coating can increase the corrosion resistance of galvanized steel sheet if the impedance value and the polarization resistance increase. The adhesion of the coating is grade 1. The coating flexibility is T-bend 1.
