Abstract: Tribological characteristics of fine-grained WC-8 wt%Ni with different surface finishing conditions corresponding to sequential wire electrical discharge machining (wire-EDM) or grinding were investigated by performing dry reciprocating sliding experiments on TE77 pin-on-plate equipment with WC-6 wt%Co as mating material. Surface finishes and wear surfaces were characterized using surface topography scanning, SEM analysis and EDX spectrometry. The decreased wear resistance due to wire-EDM could be linked to flexural strength properties as well as XRD measurements revealing tensile residual stresses on wire-EDM surfaces, in contrast with the compressive stress state on ground surfaces. Substantial improvement of wear resistance was accomplished with finer-executed EDM steps. (C) 2010 Elsevier Ltd. All rights reserved.
