The research studied the feasibility of strengthening WC-CO cermets by adding refractory oxides to the binder phase. Cemented carbides containing 0.06 to 1.5 vol. % finely dispersed oxide particles in cobalt powder, prior to liquid phase sintering, were densified and compared to undoped control powders. Three different processes for dispersing refractory oxides in cobalt metal were investigated. Results suggest that the oxide particles coalesced and/or segregated to WC-CO interfaces during the liquid-phase sintering process.
