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 μ 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.
