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.

Nickel Binder

At present, cobalt is the most commonly used binder material in tungsten carbide based hardmetals. Current research on sliding wear performance of these cemented carbides, however, reveals promising results for nickel binder as well. Test samples of WC-Co and WC-Ni hardmetals have been machined and surface finished by wire-EDM and grinding. From comparative dry sliding pin-on-plate experiments on wire-EDM’ed, ground and polished grades, correlations are derived between wear volume loss and friction on the one hand and contact pressure, sliding distance, binder phase and microstructure on the other hand. The lowest wear levels are encountered with polished cemented carbides. The EDM induced surface modification turns out to deteriorate wear resistance, especially during the running-in stage of sliding. These findings are in agreement with Xray diffraction measurements of the residual stress level in the WC phase.

This paper presents an experimental evaluation of friction and wear properties of WC-Cocemented carbides. A comparison is made between unlubricated rotating and linearly reciprocating pin-onplate sliding pairs. The plate specimens were WC-10wt%Co grades surface finished by polishing orsequential wire-EDM steps, whereas WC-6wt%Co pins were used as counter body. The tests were carriedout at room temperature using a sliding speed of 0.30m/s and mean Hertzain contact pressures of 1.76 and2.08 GPa, i.e., normal contact loads of 15N and 25N, respectively. The worn surfaces on plate sampleswere quantified in terms of 2–D wear profiles obtained by means of surface topography scanningequipment. Wear mechanisms such as polishing and abrasion were identified using optical microscopy.Inferior tribological characteristics for wire-EDM surface finish compared to polishing were found. Higherfriction coefficient and wear levels were measured in unidirectional rotating sliding experiments comparedto linearly reciprocating test conditions.

Increasing Load

The effect of load on linear reciprocating sliding friction and wear behavior in a Zr55Cu30Ni5Al10 bulk metallic glass was investigated. With increasing load, the average friction coefficient descends, while the grinding trace width increases. The grinding traces exhibit smooth linear furrows. The larger the load is, the more serious the wear extent exhibits. Under smaller loads, the wear mechanism inclines to a combined result of slight bite or bite welding and continuous wear. While with the increase of load, the wear mechanism changes gradually to the combined effects of continuous wear, occlusion or bite welding, adhesive wear and abrasive wear.
