| Abstract: | The inhibition effect of organic amines on LY12 aluminum alloy in 3.5%NaCl solution was studied by experiments with electrochemical method,scanning electronic microscopy (SEM) and corrosion fatigue.The experimental results showed that the organic amines had a good inhibitive efficiency and inhibited the pitting corrosion of the alloy to some extent. The CF experiments showed that the organic amines increased the CF life of aluminum alloy in 3.5%NaCl solution.Furthermore,iso-propylamine is even better than benzylamine in increasing CF lifetime of LY12. |
