Abstract EN
Performance of zinc yellow polypropylene-coated aluminum alloy 7B04 during accelerated degradation test is studied using electrochemical impedance spectroscopy (EIS).
It has been found that the zinc yellow polypropylene paint has few flaw and acts as a pure capacitance before accelerated test.
After 336-hour exposure to the test, the impedance spectroscopy shows two time constants, and water has reached to the aluminum alloy/paint interface and forms corrosive microcell.
For the scratched samples, the reaction of metal corrosion and the hydrolysis of zinc yellow ion can occur simultaneously.
The impedance spectroscopy indicates inductance after 1008-hour exposure to the test, but the inductance disappears after 1344-hour exposure and the passivation film has pitting corrosion.
