中文摘要:
      通过氟钛酸改性 KH858 +KH580 混合硅烷,配制出无铬钝化液,将其涂覆在热镀锌板上,经烘干、固化,形成无铬钝化膜。 测定了钝化膜的厚度、附着力和硬度;通过中性盐雾试验,研究了钝化膜的耐化学腐蚀性能;通过 Tafel 极化曲线和 EIS 图谱, 表征了钝化膜的耐电化学腐蚀性能。 结果表明: 钝化膜的平均厚度为 5 . 2μm,附着力测试的被剥离面积为 3% ,硬度为 3 H,均满足国家标准,符合工业生产要求;此外,钝化膜的耐化学腐蚀和耐电化学腐蚀性能优良,相比于改性前,其性能有较大提高。
英文摘要:
      The chrome-free passivation film was made from mixed silane KH858 and KH580 modified by fluorine titanate,which was coated on the surface of hot dip galvanized steel following drying and curing. The thickness, adhesion, hardness of film were tested; The neutral salt spray testing was done to research the resistance to chemical corrosion of the passive film. The anti-electrochemical resistance of the surface film was characterized by using Tafel polarization curves and electrochemical impedance spectrum techniques. The results showed that the average film thickness was 5 . 2 μm, the film stripped area was 3 % and the film hardness was 3 H, which may meet with the national standard and industrial production requirements. Furthermore, the film's anti-corrosion to chemistry and electrochemistry was excellent . The performance of organic silane composite passivation film modified by fluorine titanate was obviously better than the film without any modification.
