摘要

应用扫描电子显微镜(SEM)、X射线衍射(XRD)、失重法和电化学方法,研究了硬态铝箔和软态铝箔的成分差别及其腐蚀行为.结果表明,硬态铝箔和软态铝箔在表面形貌、元素成分和晶型结构上均有差异.软态铝箔比硬态铝箔更适合于在低酸度条件下进行腐蚀,这为研发电容器制作工艺的低酸度体系腐蚀提供了参考.

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.
