Abstract

Scanning electron microscopy(SEM),X-ray diffraction(XRD),weight-loss method and electrochemical testing method were employed to study the chemical compositions and corrosion behaviors of hard foil and soft foil.The results showed that the surface morphology,chemical composition and crystal structure of hard foil and soft foil are different.It is found from electrochemical tests that the soft foil is suitable to the corrosion under low acidity conditions,which provides the base for developing the corrosion techniques under low acidity conditions.

Keywords
