In this study, the effect of nickel coating and performance of porous silicon carbide structures, by an electroless coating method, was investigated. Silicon carbide powders of 30 μm and bind bentonite powders of 20 μm were mixed, and a slurry was obtained. This mixture was then absorbed into the polymeric sponge template. The structures were kept in the furnace until 1300 °C; then both water and polyurethane were removed from the structure, and the remaining particles were sintered to each other. In order to improve the wetting behavior of the aluminum composite, the porous silicon carbide structures obtained were coated with the electroless coating method. AlSi10Mg aluminum casting alloy was infiltrated into the nickel-coated porous structures by a pressure die casting method. In order to examine the coating performance, microstructure, and element analysis, both porous silicon carbide structures and aluminum composites were performed. Density, according to the Archimedes principle, and porosity measurements were made on all aluminum composites. As a result, the positive effect of nickel coating on wetting in aluminum matrix composite systems was confirmed by obtaining a value close to theoretical density with 99.75%.
