| Research Abstract |
In order to develop a high corrosion-resistant Mg-Li alloy in aqueous environments, the Mg-Li alloy thin film having continuous Li-content depend on the location on the substrate are synthesized by using the ion-beam-sputter-deposition method. The corrosion resistance on each microscopic continuous part of Mg-Li thin film are evacuated by the local electrochemistry measurement according to the combinatorial approach method.
To estimate of the corrosion-resistant of the specimen on each microscopic part of the film, the local electrochemistry measurement which used a micro- electrochemistry cell are carried out on the same specimen, continuously. In addition, to reveal the improvement mechanism for the corrosion behavior of Mg-Li alloy, the chemical state of the early stage oxidized film and passive film on the Mg-Li alloy are analyzed by X-ray photoelectron spectroscopy(XPS), Auger electron spectroscopy(AES) and in-situ ellipsometry on the the Mg-Li alloy film depend on Li content.
