摘要：

An epoxy coating and a combination of chemical passivation in rare earth metal chlorides with the polymer coating provide excellent corrosion resistance for Al 6061, Al/SiC, Al/graphite and Al-Li 2091-T6. An accelerated corrosion test for polymer coatings based on electrochemical impedance spectroscopy (EIS) and a model for the impedance of polymer coated samples with an artificial defect have been developed to evaluate the quality of coatings and to predict the lifetime of coated metals in a short time.
