Protection of D16 Alloy against Corrosion in Neutral Aqueous Solutions and in an Aggressive Atmosphere Using Organic Inhibitors

摘要

The possibilities of protecting the aluminum alloy D16 with organic corrosion inhibitors are considered. The protective ability of the obtained nanoscale layers was evaluated by an express method (drop test), tests in a heat and moisture chamber, salt spraying, and electrochemical impedance spectroscopy. The efficiency of treating D16 in aqueous solutions of organic inhibitors is correlated with the protective ability of chromate films.
