摘　　要：将自组装膜和稀土转化膜结合可以强化各自的优点,制成的复合膜的耐蚀性能得到极大提高,目前此类研究还不系统。在铜片表面先自组装硅烷膜,再铈盐转化成膜,以复合膜耐蚀性为评价指标,对自组装时间、铈盐转化时间进行优化,对优化条件制成的复合膜的耐蚀性进行研究,与单一的硅烷自组装膜、铈盐转化膜进行比较,并对硅烷-铈盐复合膜的成膜、耐蚀机理进行了探讨。结果表明:硅烷自组装膜与铈盐转化膜的最佳成膜时间分别为10.0 min和1.0 min,硅烷-铈盐复合膜对铜的防腐蚀性能比2种单一膜的有明显提高。Silane self-assembled film was firstly prepared on the surface of Cu plate.Cerium salt conversion of resultant silane self-assembled film was then conducted to afford composite film.The self-assembled time of the silane film and the conversion time of the cerium salt conversion film were optimized in relation to the corrosion resistance of the title composite film,and the corrosion resistance of the composite film obtained under the optimized conditions was evaluated with self-assembled silane film and cerium salt conversion film as references.Moreover,the formation and corrosion mechanisms of silane-cerium salt composite film were investigated.Results indicated that the optimized film-formation time for self-assembled silane film and cerium salt conversion film was 10.0 min and 1.0 min,respectively.As-prepared silane-cerium salt conversion composite film possessed much better corrosion resistance than self-assembled silane film and cerium salt conversion film.
