摘要：
To improve the surface wear resistance of the ceramic coating fabricated by micro-arc oxidation (MAO) on AZ91D magnesium alloy ceramic coatings embedded with SIC nano-particles at different current frequency (500 Hz 700 Hz and 900 Hz) were produced during the MAO process The morphology and phase composition of the coatings were investigated by scanning electron microscopy (SEM) field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD) The surface roughness of the coatings was characterized by confocal laser scanning microscopy (CLSM) Simultaneously the tribological properties of the composite coatings were evaluated by using a universal materials tester (UMT) The results shows that the wear resistance of the ceramic coatings with SiC nano-particles was improved significantly compared to the ceramic coatings without SIC nano-particles Furthermore the composite coating formed at current frequency 900 Hz showed the better wear resistance than the others
