Abstract

In this paper, X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES) were applied to investigate passive films formed on aluminum alloy in 0.5 kmol m-3 H3BO3/0.05 kmol m-3 Na2B4O7 with different metal cations. The metal cation is classified by metal cation hardness, X, which are calculated based on the concept of hard and soft acids and bases (HSAB) of the acid and base in Lewis’s rule. From XPS analysis, the metal cations with X>4 were incorporated in passive films. The area-selected surface analysis of AES was also introduced.
