The effects of Fe and Cu on the wear behaviour of W-Ni alloys is investigated. W-Ni-Fe and W-Ni-Cu alloys are produced with six different compositions by the powder metallurgy technique. The microstructure is examined after shaping and sintering. Electron microscopy (SEM+EDS) and X-ray diffraction (XRD) are used to characterize the density, hardness, and grain size of W-Ni-Fe and W-Ni-Cu alloys produced by powder metallurgy technique. A pin-on-disc apparatus is used for the wear tests. All of the samples are tested under loads of 20 and 30 N, at a rate of 1 m/s and for five different sliding distances. It is found that, in Fe and Cu alloys, an increase in the W amount results in an increase in density and hardness. Furthermore, an increase in the W amount leads to a decrease in the amount of the binding phase for W-Ni-Fe and W-Ni-Cu alloys with a W content of 90, 93, and 97%, and resultes in reduced weight loss for W-Ni-Fe alloys.
