AB  - The deposition of a uniform Nickel Phosphorous (Ni-P) coating on Silicon Carbide (SiC) particles by
an electroless method was investigated in this research. The electroless bath is prepared with nickel sulfate and
sodium hypophosphite at pH value of 8. In this research the effect of two different particle size 10 and 80 μm
and the influence of both time and temperature on (Ni-P) coating deposition were studied. (Ni-P) coating is
analyzed by optical microscopy (SEM) and (EDS). Uniformity in coating were obtained for pre-treated SiC with
particle size of 80 μm at bath temperature of 70°C and stirring time of 15 min. Non-uniform coating was noted
in SiC of 10 μm and in SiC of 80 μm during deposition time of 5 and 10 min. Electroless bath temperature of 50,
60 and 80°C resulted in the formation of segregated clusters of (Ni-P) leading in many uncoated parts of SiC
particles.
