Accelerated climatic testing of composite coatings on AMg3 aluminum alloy in salt spray medium. V.S. FILONINA, K.V. NADARAIA, A.S. GNEDENKOV, I.M. IMSHINETSKY, D.V. MASHTALYAR, I.E. VYALIY, V.S. EGORKIN, S.L. SINEBRYUKHOV, S.V. GNEDENKOV (Institute of Chemistry, FEB RAS, Vladivostok).
The results of accelerated climatic tests of composite polymer-containing coatings on the AMg3 aluminum alloy are presented in the paper. According to the results of the studies carried out, a positive effect of the penetrated composite material into the pores of a PEO-coating on the wettability and corrosion resistance of the test samples under conditions of long-term exposure to salt fog has been revealed. The highest corrosion resistance was demonstrated by samples with a fourfold (СС-4x) application of superdispersed polytetrafluoroethylene.
