| 摘 要： | 常温下对6061铝合金表面转化膜进行了研究,分别讨论了Zn2+、PO43-、F-、Fe2+、Ce3+、Cu2+对磷化膜质量的影响,同时通过正交试验和综合评定法确定出了一种不含铬的铝合金稀土磷化液的介质组成及相应的工艺参数。转化膜成分含有Zn、Fe、P、O、Ce的复合磷酸盐,结果表明:此磷化液在常温下,8 m in即可在6061铝合金表面上生成一层均匀、致密、耐蚀性良好的磷化膜。该方法工艺简单,在整个工艺过程中不需要使用铬元素,对环境影响小,具有良好的应用前景。

| Abstract: | Conversion coating on 6061 aluminum alloy surface has been studied under ordinary temperature.The effects of Zn2+,PO3-4,F-,Fe2+,Ce3+,Cu2+ on the quality of phosphating coating were discussed.In addition,by use of orthogonal experiment and synthetic evaluation method,the composition and corresponding process parameters of a chromium-free rare earth phosphating solution are determined.The conversion film conponent contains compound phospates of Zn,Fe,P,O,Ce.The results show that this phosphating solution at r... |
