“…Particle addition into PEO coatings is a novel approach to obtain a type of in situ sealing. Arrabal et al [7,8] fabricated coatings with ZrO 2 nanoparticle additions and assumed that the particles were transferred to the interface between the inner/outer layer through short-circuit paths in the outer layer. Lee et al demonstrated that the electrophoretic mobility and mechanical mixing in molten magnesium oxide were main factors leading to particle incorporation [9].…”

“…Up to now, researchers have been making great efforts to overcome this problem. One effort is to adjust the microstructure and composition of ceramic coatings by using a modified electrolyte with additives such as nano/microparticles or sol [24][25][26][27][28][29]. Another effort is to form composite coatings by a combined process including MAO/DLC [30], MAO/sol-gel [31], and MAO/ organic polymer [32].…”

We investigate the influence of silica sol addition on the ceramic coatings of Mg-Li alloy by plasma electrolytic oxidation (PEO) in an alkaline silicate electrolyte. Scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and energy dispersive spectroscopy are employed to characterize the microstructure and composition of the ceramic coatings. The anti-corrosion behavior of the ceramic coatings is evaluated by potentiodynamic polarization measurements in conjunction with electrochemical impedance analysis. The ceramic coating formed in the electrolyte containing silica sol contains SiO 2 and Mg 2 SiO 4 phase and has more uniform morphology and higher corrosion resistance than that formed in the electrolyte without addition of silica sol.
