The effect of curing conditions on anti-corrosion properties of cathodic electrodeposition coatings as revealed by EIS and salt spray tests

There are several methods to evaluate the anticorrosion properties of protective coatings. The protective coating that is used in automotive industry is cathodic electrocoating[1]. Evaluation of corrosion resistance of coated metals include two general methods: electrochemical and non-electrochemical methods[2]. There have been several articles written in the past which the comparise test of EIS and salt spray test for protective coatings. For example, Poalman et al. [3] evaluated the barrier mechanism of epoxy based coatings that electrodeposited on Al surface by Both methods which showed similar results
