| 摘 要： | 利用Ｘ射线光电子能谱（ＸＰＳ）和Ｘ射线衍射等，研究了Ｚｎ－４８．４８Ａｌ－１。６５Ｃｕ－０．０３Ｍｇ合金液表面氧化膜微细特性。除Ａｌ２Ｏ３外，氧化膜内还有相当数量的ＺｎＯ和金属Ｚｎ存在，少量的ＭｇＯ和ＭｇＡｌ２Ｏ４明显富集在膜表面，少量金属Ｃｕ滞留于氧化膜中，氧化膜中金属离子明显过剩，计算及生产实践表明，这种氧化结果导致合金Ｚｎ和Ｍｇ含量减少，Ａｌ和Ｃｕ含量反而增加。

| Abstract: | The hoe characteristics of the Oxide am on the surface of Zn -- 48. 48Al -- 1. 6 5 Cu 0.03Mg meltl were investigated using X--ray photoelectron spectroscopy (XPS) and X--ray exaction (XRD)etc aam oxide film consists mainly of ZnO, Al2O3 and Zn while a small amount of MgO, MgAl2O4 and Cu also exist in the film. The chides of MgO and MgAl2O4 are obviously concentrated on the surface of the film. In these chides, the phenomenon of an excess of metallic ions is quit evident. In addition, it has been proved that, due to the oxidizing the contents of Zn and Mg in the melt will decrease and that of Al and Cu will increase. |
