| 中文摘要: |
| 采用双一[γ一（三乙氧基硅）丙基]四硫化物( BTESPT)硅烷钝化液对热镀铝锌钢板进行了钝化处理。研究了在50-/0NaCI溶液中未钝化、硅烷钝化及铬酸盐钝化热镀铝锌钢板的极化曲线和电化学交流阻抗谱。通过中性盐雾试验比较了硅烷钝化膜与铬酸盐钝化膜的耐蚀性能。结果表明：经硅烷钝化液钝化后的热镀铝锌钢板，其腐蚀电位和电流密度下降，极化电阻增大，硅烷钝化膜抑制了热镀铝锌钢板的腐蚀过程，使得耐蚀性能远远高于铬酸盐钝化后的热镀铝锌钢板。 |
| 英文摘要: |
| Bis-( triethoxysilylpropyl) tetrasulfide silane passivating treatment process was investigated on hot dip Al-Zn steel sheets. The electrochemical behavior of silane passivating film on hot dip Al-Zn steel sheets in 50-/o NaCl solution was studied by electrochemical polarization curve and electrochemical impedance spectroscopy measurements. The corrosion resistance of silane films was compared to chromate passivating treatment on hot dip Al-Zn steel sheets by neutral salt spray tests. Results show that the corrosion potention and corrosion current density decrease and the polarization resistance increase after silane passivating treatment. The corrosion process of hot dip Al-Zn steel sheets has been inhibited by silane passivating treatment. The corrosion resistance of silane passivating treatment is prior to that of chromate passivating treatment. |
