Wear performance of spark plasma sintered Co/WC and cBN/Co/WC composites
B Yaman, H Mandal - International Journal of Refractory Metals and Hard …, 2014 - Elsevier
The present study investigates the efficiency of spark plasma sintering (SPS) technique on
the tribological behavior of tungsten carbide composites, and aims to develop the wear
resistance of these composites by addition of cubic boron nitride (cBN). Wear tests of spark
plasma sintered 6 (wt.%) Co/WC, 25 (vol%) cBN/6Co/WC and conventionally fabricated 6
(wt.%) Co/WC as a reference sample were performed by ball-on-disk contact with dry and
rotational sliding at room temperature in order to determine the friction coefficient and wear …
