摘要

为了探究1100 铝板在阳极氧化过程中表面出现白条缺陷的原因，通过化学成分分析、宏观形貌分析、表面粗糙度分析、扫描电镜及能谱分析、X 射线衍射分析等方法，对阳极氧化后的1100 铝板表面出现的白条缺陷进行研究。结果表明:白条缺陷区域的AlFeSi 相种类、数量和面积分数都不及正常区域多，在阳极氧化后因AlFeSi相而产生的蚀坑和蚀孔少于正常区域，表面粗糙度也比正常区域小，使得白条缺陷区域在自然光下受到的漫反射少于正常区域，因此颜色上比正常区域白亮。

Abstract

In order to investigate the causes of white stripe defects on the surface of 1100 aluminum plates during the anodizing process，chemical composition analysis， macroscopic morphology analysis， surface roughness analysis， scanning electron microscopy (SEM)， energy dispersive spectroscopy (EDS) analysis and X-ray diffraction (XRD) analysis were conducted to study the white stripe defects on the surface of the anodized 1100 aluminum plates.Results showed that the types， quantities and area fractions of AlFeSi phases in the white stripe defect areas were fewer than those in the normal areas.After anodizing fewer pits and corrosion holes caused by the AlFeSi phases were found in the white stripe defect areas compared to the normal areas.The surface roughness was also smaller in the defect areas than in the normal areas，which led to less diffuse reflection under natural light in the white stripe defect areas than in the normal areas， making them appear brighter and whiter compared to the normal areas.

Key words： 1100 aluminum plate; anodizing; white stripe
