| Popis: | A new corrosion inhibitor, cerium malate, was synthesized. Its inhibiting behaviour on coupled Al2Cu-Al2CuMg-Al, Al2CuMg-Al and Al2Cu-Al was studied. Cerium malate is effective in corrosion inhibition of the three coupled systems. The inhibition mechanism of cerium malate on pitting corrosion of Al2CuMg and Al2Cu phases in AA 2024-T3 was analyzed by scanning vibrating electrode technique (SVET), atomic force microscopy (AFM) and scanning kelvin probe force microscopy (SKPFM). The results indicate that cerium malate has good inhibiting effect on AA 2024-T3. |
