Nano-sized SiC particles were codeposited with  nickel by electroplating from a nickel Watts bath and the effects of SiC content in the plating bath and stirring speed on the behaviors of Ni–SiC composite coatings were studied. The researched methods such as: electrochemical method, Scanning Electron  Microscope  (SEM  + EDX), hardness testing… were used. The result shown that the SiC concentration in bath and stirring speed strongly influenced on SiC nano-particulates amount in the coatings,  microhardness and corrosion behavior the  nanocomposite coatings.
