The deposition of metals on the ceramic particles has attracted many attentions in recent years, which
cause better wettability of ceramics during casting of metal matrix composites. In this study, the effect
of electroless parameters have been investigated on the amount of mass gain during deposition of Ni
on the SiC particles. For this purpose, pH, bath temperature, and particle size were considered as the
process parameters. Scanning electron microscopy (SEM) was used for characterizing the deposited
particles. In addition, response surface method was used for optimizing the process parameters using
Design Expert software. The results revealed that the particle size had more effect on the mass gain
compared to thepH and bath temperature. Increasing particle size and decreasing bothpH and bath
temperature caused larger amount of mass gain. The best condition for the electroless deposition of
the Ni on the SiC ceramic particles was determined as particle size of 80 μm, bath temperature of
50 °C, and pHof 8.
