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.
