Corrosion protection of Mg?SiC nanocomposite through plasma electrolytic oxidation coating process

Understanding the role of nanoparticles in magnesium (Mg)-based materials and protective coating provides valuable information to achieve an optimized combination mechanical corrosion protection properties Mg nanocomposites. The present study investigates effects SiC on behavior structure Mg-SiC composites substrates coated by plasma electrolytic oxidation (PEO). Moreover, influence different volume fractions SiCn up 10% galvanic reactions between matrix particles was also investigated. morphology, distribution phases, microstructure were characterized SEM, EDAX, X-ray photoelectron spectroscopy, XRD. resistance samples determined through dynamic polarization electrochemical impedance spectroscopy tests before after PEO treatment. results indicate that nanocomposite with 1 vol% (M1Sn) shows higher than a percentage SiCn, as well sample without particles.
