Abstract
Microstructure analysis and mechanical characterization were performed on newly developed WC based and yttria stabilized tetragonal zirconia (ZrO2) doped cermets with nickel metal binder produced by hot isostatic pressing. The cermets have reached higher than 99% of theoretical density after processing at 1700 0C and 206 MPa for 1 hour. Zirconia has appeared to form agglomerates of about 1 µm and suppressed carbide grains growth. Hardness of zirconia doped materials was of the same magnitude and fracture toughness was slightly higher as compared to conventionally produced WC-Co hardmetals of the same metal binder content while wear resistance in conditions of erosion and abrasion in silica media is increased by two fold.
