摘　　要：由Ｎａ２ＭｏＯ４·２Ｈ２Ｏ和Ｎａ２ＨＥＤＰ·５Ｈ２Ｏ合成了有机膦合钼聚多酸盐Ｎａ８［（ＨＥＤＰ）２Ｍｏ５Ｏ２１］·５Ｈ２Ｏ。用Ｎａ８［（ＨＥＤＰ）２Ｍｏ５Ｏ２１］·５Ｈ２Ｏ的溶液处理Ａ３钢，获得了具有一定耐蚀性的黄色转化膜，适宜的工艺条件为：浓度１６ｇ·Ｌ－１，ｐＨ３．５，温度５０℃，时间８０ｓ。本文还报告了膜层的ＸＰＳ和ＡＥＳ分析结果。Na 8[(HEDP) 2Mo 5O 21 ]·5H 2O was synthesized by Na 2MoO 4·2H 2O and Na 2HEDP·5H 2O. A yellow conversion film was obtained on A3 steel surface by treating A3 steel with the solution of Na 8[(HEDP) 2Mo 5O 21 ]·5H 2O. The suitable technical conditions were established as follows: concentration 16 g·L -1 ,pH 3.5, temperature 50℃, and time 80 s.The analysis results for the film by XPS and AES are also reported.
