From comparative dry sliding pin-on-plate experiments on distinctive WC-Co and WC-Ni cemented carbides, machined by grinding or wire-EDM, correlations are derived between wear rate, wear volume and coefficient of friction and contact load, sliding distance, microstructure and surface finish condition. The EDM induced surface modification turns out to deteriorate wear resistance, especially during the wear-in stage of sliding. These findings are in agreement with X-ray diffraction measurements of the residual stress level in the WC phase.
