Abstract

Abstract:

The morphology of the protection film of AMT formed on bronze has been observed by scanning tunneling microscopy in angstrom scale. Three to five ellipse units join together to forma linear structure. Many such linear structures make up the protection film to prevent corrosion process of bronze. After analysis the reactivity of AMT with Cu (Ⅱ ) by XPS,XAES and IR, the conclusion has been obtained as follow: corrosion product Cu(Ⅱ ) combined with AMT forming a complex compound which deposits on the bronze from the protection film. The structure has been describe in the letter.

Key words: Protection film, Inhibitor, Bronze, STM
