摘要：

Up to 50 vol% of TiB2, TiC0.5N0.5, TiN, or TiC was added to Y2O3-stabilized tetragonal ZrO2 polycrystals (Y-TZP) and hot pressed under vacuum. The influence of the type of secondary phase on the microstructure and mechanical properties was studied, as a function of the hot-pressing temperature. The influence of the secondary-phase content on the mechanical properties was studied by varying the TIE, content up to 50 vol%. Fully dense Y-TZP-based composites with very high toughness (up to 10 MPa.m(1/2)), excellent bending strength (up to 1237 MPa), and increased hardness, with respect to ZrO2 (Vickers hardness up to 1450 kg/mm(2)), were obtained.
