在铝材及铝制品的电解抛光过程中可产生种种缺陷，其中最常见的是白霜、点腐蚀、气泡等。叙述了这些缺陷的产生原因、预防与消除措施。产生白霜的主要原因是磷酸浓度过大、电解温度低、硫酸稀、水少。铬酸含量高、温度过高、电流密度大、硫酸含量少，易出现点腐蚀。电解抛光的铝制品具有最大的反射率、最强的抗蚀性与最长的寿命 Aluminum and aluminum products in the electrolytic polishing process can have a variety of defects, the most common are hoarfrost, pitting, bubbles and so on. Describes the causes of these defects, prevention and elimination measures. The main reason for the hoarfrost is phosphoric acid concentration is too large, the electrolysis temperature is low, sulfuric acid is thin, less water. Chromic acid content is high, the temperature is too high, the current density, less sulfuric acid, prone to pitting. Electropolished aluminum products have the highest reflectivity, the strongest corrosion resistance and the longest life expectancy
