| 中文摘要 | The corrosion mechanism of Mg-Al-CO32- hydrotalcite film is discussed based on its corrosion behavior and the anion-exchange or adsorption effect of Cl-. The results demonstrate that the film is very compact and acts as a barrier against Cl- attack in the early stage. Then the surface of the film is dissolved gradually due to its instability in aqueous solutions. Only after eliminating CO32-, Cl- can insert into the hydrotalcite interlayer to balance charges. Cl- cannot substitute CO32- just in NaCl solution, but can adsorb on active spots of the film to accelerate the decomposition. (C) 2012 Elsevier Ltd. All rights reserved. |
