The article presents the results of a study of the anti-corrosion properties of composite materials based on epoxy resin modified with a mixture of AGM-9 and TGM-3 in a ratio of 1:3 and treated with zinc oxide nanoparticles. It is established that the coating of metals with epoxy oligomers and zinc nanoparticles significantly increases their resistance to corrosion. After holding in a 3.5% NaCl solution for 90 days, the hardness of metals without coating decreases by 22%, modified with AGM-9 and TGM-3 composites - by 11%, and modified with epoxy oligomers in combination with zinc nanoparticles-by only 3 %.
