Abstract

This work presents the results of research on the anti-corrosion ability of AC-2HM complex additive system consisting of traditional additives combining organic acids on multi-metal systems including steel, copper, aluminum in corrosion water. The results show that the optimal concentration of the additive is 5% of the amount of cooling water. Research results of the electrochemical method show that the additive system has the ability to inhibit corrosion up to over 97%-99% under normal conditions. At high temperatures, the corrosion inhibition efficiency is reduced to 89-94%.
