Electro-diffraction analysis demonstrated that amorphous structure was formed after IBM. In the deeper layer a metastable phase was formed. Electro-diffraction and TEM exam have been used to investigate the transformation from amorphism to crystal when heating-up. The electrochemical results have shown that the anodic current

and
I

were reduced remarkably for passivation after IBM.
