Description
Summary:Nickel–Si3N4 composites were generated by means of pulse-reverse (PR) electrodeposition technique. The corrosion rate was calculated for the composites by electrochemical methods such as polarisation and impedance methods. Composites were characterised by scanning electron microscope (SEM) and X-ray diffractometer (XRD) to evaluate their microstructures. Coatings obtained by PR method shows more corrosion resistance than DC generated coatings.
