In recent years, compacted graphite cast iron was a good substitute for several industrial applications that involve wear. The adhesive wear characteristics of compacted graphite iron and flake graphite iron were investigated in this work. It was found that the coefficient of friction is lower for compacted graphite iron. For both cast irons, the influence of microstructure and graphite morphol. on the wear process was studied and discussed in this paper. Compacted graphite iron seems to have good potential as a substitute material for applications involving adhesive wear.
