In this paper, Ni-SiC nanocomposite coatings were applied on AZ91 magnesium alloy from Watts bath containing different amounts of SiC content by pulse electrodeposition technique. The morphology and phase analysis were carried out by Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) analysis, respectively. Microhardness of specimens was measured and the results revealed a significant enhancement from 74 H for bare AZ91 magnesium alloy to 523 HV for the specimen coated in the bath containing 15 g.L–1 SiC. The Corrosion behavior of the samples was studied by potentiodaynamic polarization, and the obtained data showed superior corrosion resistance for coated AZ91 magnesium alloy, i.e. the corrosion current density decreased from 2.69 mA.cm–2, for the uncoated sample, to 0.00046 mA.cm–2, for coated specimen in the bath containing 15 g.L–1 SiC and the corrosion potential increased from – 2.069 V to – 0.33 V at the same conditions.
