Abstract

Abrasive wear of a series of WC-(5–14 wt.%)Co hardmetals was investigated employing P800 and P120 SiC abrasive papers. It was found that if fine abradant was utilized, submicron grades demonstrated substantially higher wear rates than the coarse grades. Such a behaviour was associated to different wear mechanisms operating for fine and coarse grades and correlated to the ratio of the abrasive size to size of the hard WC phase.
