摘　　要：利用浸液法在锌镀层上获得混合稀土转化膜，研究了处理溶液的浓度、ｐＨ、温度、促进剂Ｈ２Ｏ２的含量及处理时间等因素对膜层耐蚀性的影响，从而确定了适宜的工艺条件。用俄歇电子能谱（ＡＥＳ）对膜层的组成。A conversion film was obtained on zinc deposit by immering zinc deposit specimens in a mixed rare earth solution. Several factors to affect the anti corrosion efficiency of the conversion film were studied. The suitable conditions of technology were established. The composition and the thickness of the conversion film were determined by Auger electron spectroscopy(AES).
