The tribological and mechanical behavior of coated tools depends not only on intrinsic properties of the deposited film but also on substrate surface and subsurface properties – such as topography and residual stress state – as well as on interface adhesion strength. It is particularly true in the case of coated tools based on WC-Co cemented carbides (backbone materials of the tool manufacturin...

Drill bits equipped with WC-Co cemented carbide buttons offer great performance in many rock drilling applications. Generally, the wear of these against is gradual and moderate, or even slow depending on conditions. However, Co binder has recently been found to cause health issues an alternative binder, which does not compromise carbide, needed. In present work, WC-Fe WC-Ni investigated compare...

This work aims to explore WC-G201 high entropy cemented carbides properties fabricated by spark plasma sintering with AlCoCrFeNiTi0.2 and WC as binder phase hard respectively. powder were mixed at the mass ratio of 5: 95, 10: 90 15: 85 respectively, then via SPS 1300℃ for 5min. The results show that has good wettability WC, increase content, hardness alloy decreases gradually, fracture toughnes...
