摘要: 用X射线光电子能谱(XP3)分别对铝铜合金的重铬酸钾钝化膜和8108钝化膜的组成进行了分析。结果表明,重铬酸钾钝化膜的主要成份是Al_2O_3,此外还有一定量的Cr_2O_3。证实了在重铬酸钾钝化膜中是有Cr_2O_3存在。在8108钝化膜中,除主要成份Al_2O_3外,还观察到有AlN和金属氮铬合物。此外,铝铜合金的这二种钝化膜中均未测到铜的信息,说明铜被覆盖在钝化膜之下。但含量较低的镁却富集在表层。
Abstract:In this paper, the passive films of aluminum-copper alloy treated with K_2Cr_2O_7 and nitrogen-containing passivation agent(8108) were studied by XPS respectively. The results show that the former contains Cr_2O_3 species besides the main component A1_2O_3, the latter contains AlN and aitrogencontaining complexes in addition to Al_2O_3.It is interesting to note that no opper signal can be detected on the surfaces of both passive films. Both films, moreover, show a definite mangnesium peak although magnesium content in the alloy is very low.
