Spheroidal graphite cast iron composites with SiC particles dispersed in the surface region were made by vacuum assist casting. Although melt infiltration could not be carried out when the melt was poured without vacuum assist, it was successfully carried out by vacuum assist casting when the SiC particle volume fraction in the preform and preform thickness were optimized. The matrix of the composite was spheroidal graphite cast iron consisting of fine graphite particles, ferrite, and pearite. When the C content was 3.5mass% and the Si content was 2.5mass% in the spheroidal graphite cast iron, a product consisting mainly of Fe3Si was clearly observed at the interface between the matrix and SiC particles. This was formed by the reaction between the cast iron melt and SiC particles during the infiltration. The increase in Si content in the cast iron tends to inhibit reaction.
