Effect of corrosion product on corrosion behavior of PEO coating based on its structure and semiconducting properties
Source abstract
Abstract
Structure and semiconducting properties of corrosion products on plasma electrolyte oxidation (PEO) treated magnesium alloy was investigated with the process of immersion corrosion in 3.5 wt% NaCl solution. It was found that the structure of corrosion products transformed from flaky to dense granular-like, which effectively improved corrosion resistance of PEO coating. At the same time, the generation of corrosion products repaired the oxygen vacancies of original PEO coating, thus inducing semiconducting characters of coating transition from n-type to p-type. This will reduce the adsorption of corrosive ions, and further prolonging protection performance of PEO coating.
