In　the　present　work,　particles　of　SiC　were　applied　to　the　micro-arc　oxidation　(MAO)　treatment　of　Ti6Al4V,　characterization　of　MAO　coatings　with　different　SiC　particle　concentration　were　evaluated.　X-Ray　Diffraction　(XRD)　and　Scanning　Electron　Microscope　(SEM)　results　show　that　the　structure　and　morphology　of　MAO　ceramic　coatings　could　change　with　different　amounts　of　SiC　in　the　electrolyte.　Both　of　the　number　and　size　of　the　pores　on　the　ceramic　coating　surface　were　decreased,　while　the　layer　thickness　increased　with　the　increase　in　SiC　particles　in　the　electrolyte.　A　dense　double-layer　structure　coating　composed　of　a　Ti-based　layer　and　a　SiC-based　layer　with　a　thickness　of　about　40　mu　m　was　prepared.　It　was　shown　that　the　addition　of　SiC　particles　participated　in　the　process　of　micro-arc　oxidation　and　changed　the　microstructure　of　MAO　coating.
