| 摘 要： | 利用不同的浸泡处理,制备了单纯铈盐转化膜、KH560硅烷转化膜、铈盐硅烷转化膜和硅烷铈盐4种转化膜,结合FT-IR、SEM、EDS、Tafel、EIS等分析手段,对比考察了4种转化膜对镁合金耐腐蚀能力的情况,结果表明:铈盐转化膜和硅烷转化膜之间没有相互影响,均具有独立成膜的能力;铈盐硅烷转化膜和硅烷铈盐转化膜比单纯的铈盐转化膜和单纯的硅烷转化膜具有更好的耐腐蚀能力;铈盐硅烷转化膜和硅烷铈盐转化膜耐腐蚀能力的差别和原因,尚需要进一步的试验研究。

| Abstract: | With different immersion treatment,four kinds of conversion coatings including pure cerium conversion,KH560 silane conversion,cerium-silane conversion and silane-cerium conversion coatings were prepared.The corrosion resistance of four kinds of conversion coatings were studied and compared by use of IR,SEM,EDS,Tafel and EIS.The results showed that there were no interaction between cerium coating and silane coating,and they could form conversion coating independently.The cerium-silane conversion coating and ... |
