- Abstract
- The corrosion protection performance of epoxy-treated fluoropolymer-coated
AA 6061 T6 alloy was studied. Two types of fluoropolymer with different
fluorine ratios (FLBZ 1074 and modified FLBZ 1074) were applied as top
coatings. Electrochemical impedance spectroscopy (EIS) was used to
investigate the corrosion resistance of such coatings in 3.5% NaCl solution
under uniform and scratched conditions. Uniform coatings showed excellent
corrosion protection also after 4 months of immersion in NaCl. Conversely,
the corrosion rates increased dramatically under the scratched conditions
after less than 1 month of immersion in NaCl due to filiform corrosion. A
general equivalent circuit model has been used to analyse the impedance
data in terms of reactions occurring during the interaction of the coated
specimens with the environment. Based on the results of this analysis,
together with the visual inspection, FLBZ 1074 coating was found to be more
efficient than the modified FLBZ 1074 coating in providing corrosion
protection in NaCl solution. (literal)
