摘要:
磷化处理是钢铁材料防腐前处理的重要工序，磷化处理不当导致的磷化膜缺陷严重影响后续的电泳、喷漆等处理过程，最终会造成整体材料的外观质量、耐腐蚀性能不合格。为了提高磷化膜质量，采用扫描电镜、能谱仪、辉光放电原子发射光谱等系统分析了磷化生产线中常出现的磷化膜白斑缺陷。结果发现：白斑位置磷化膜异常薄且平整，对光线的反射率提高，外观上表现比正常位置亮，体现为白斑缺陷。去除磷化膜后，通过对镀层表面形貌的对比分析揭示了白斑缺陷产生的原因。
Abstract:
： Phosphating is an important anti-corrosion pretreatment of iron and steel materials. The defects of phosphating film caused by improper phosphating process seriously affect the subsequent electrophoresis ， painting and other treatment processes ， and will eventually lead to the bad appearance quality and corrosion resistance of the whole material. In this paper ， the scanning electron microscope ， energy dispersive spectrometer and glow discharge atomic emission spectrometry were used to systematically analyze the white spot defects of phosphating film in phosphating production line. The results showed that the phosphating film at the white spot position was extremely thin and flat ， the reflectivity of light was improved ， and the appearance was brighter than the normal position ， which was reflected as white spot defects. After the phosphating film was removed ， t he causes of white spot defects were revealed through the comparative analysis of the surface morphology of the coating.
