Abstract

The most known method of protection against corrosion of aluminum and its alloys is sulfuric acid anodic oxidation. The oxidized surface has a significant ability to resist aggressive external factors, high adhesion properties. However, the coating requires an additional treatment consisting of soaking in hot solutions, called filling. The article presents the results of research aimed at the development of the composition and a new method of filling anodic-oxide coating, the possibility of using this composition as a corrosion inhibitor is evaluated.
