| 中文摘要: |
| 采用浸没法,以纯Mg及AZ91D,AZ61,ZK60,ZM21镁合金为基体材料,在植酸水溶液中制备植酸转化膜。观察了植酸转化膜的形貌,分析了转化膜的元素组成及浓度分布,进而研究了镁合金的微观结构对制备表面植酸转化膜的影响。结果表明:合金元素对植酸转化膜的形成起着决定性的作用,高价合金元素(Al和Zr)比低价合金元素(Zn和Mn)更有利于植酸转化膜的形成,以固溶体存在的Al比以化合态(Mg17Al12)存在的Al更有利于转化膜的形成。 |
| 英文摘要: |
| To study the influence of microstructure of magnesium alloys on preparation of phytic acid conversion coatings, the phytic acid coatings were prepared on AZ91D,AZ61,ZK60,ZM21 magnesium alloys in phytic acid aqueous solution by immersion method, and pure magnesium were used to compare. The surface morphologies of conversion coating were observed, and surface element compositions and concentration distribution of conversion coating were analyzed, and the effect of the microstructure on preparation of phytic acid conversion coating was studied. The results show that alloying elements play a definitive role in forming conversion coatings. Tetravalent and trivalent alloying elements are more helpful than divalent alloying elements. Alloying elements dissolved in the magnesium matrix(alpha-phase)are more beneficial for forming coatings than that in the second-p hase. |
