摘　　要：铝合金因其重量低、良好的强度、刚度和塑性等特点,广泛用于航空制造产业。铝合金基体在使用前会设计一个较为复杂的组合防护方案来提高耐蚀性,通常使用的方案是阳极氧化加漆层防护。随着航空制造业向高端化和绿色化发展,常用的铬酸阳极氧化因六价铬的毒性被替代的声音越发强烈。本文从发明历史,性能,环保影响、使用成本几个维度,综合比较了铬酸、硼酸-硫酸、硫酸、酒石酸-硫酸阳极氧化的工艺,研究显示硼酸-硫酸阳极氧化在耐蚀性、疲劳极限、绿色环保、使用成本均有可替代铬酸阳极氧化的优势。Aluminum alloys are widely used in the aviation manufacturing industry due to their low weight,good strength,stiffness,and plasticity.Before use,an aluminum alloy substrate is designed with a complex combination protection scheme to improve corrosion resistance.The commonly used scheme is anodizing with a paint layer for protection.With the development of high-end and green aviation manufacturing industry,the voice of commonly used chromic acid anodizing being replaced due to the toxicity of hexavalent Cr has become increasingly strong.This article comprehensively compares the processes of chromic acid,boric acid sulfuric acid,sulfuric acid,and tartaric acid sulfuric acid anodizing from the dimensions of invention history,performance,environmental impact,and usage cost.The research shows that boric acid sulfuric acid anodizing has advantages in corrosion resistance,fatigue limit,green environmental protection,and cost of use,which can replace chromic acid anodizing.
