Anticorrosion PEO Coatings Impregnated with Corrosion Inhibitors on AMg3 Alloy
摘要
Abstract—
The protective coating with a microtubular structure is formed by plasma electrolytic oxidation on an AMg3 aluminum alloy (Al–Mg system) in a tartrate–fluoride electrolyte. This protective layer is further modified using azole group corrosion inhibitors (1,2,4-triazole, benzotriazole) and polymer (polyvinylidene fluoride). The morphology, composition, corrosion mechanism, and protective properties of the formed coatings are studied.
