摘要：

Zirconium oxide (zirconia) ZrO2 is widely used for applications in high-temperature structural materials. In this work, yttria-stabilized zirconia has been studied. Series of specimens of ZrO2 ceramics stabilized with 6, 7, and 8 mol% Y2O3 were prepared using the conventional sintering technique. Four sintering temperatures (1450, 1500, 1550, and 1600 degrees C) were used for the 6% yttria-stabilized zirconia series, and two sintering temperatures (1550 and 1600 degrees C) were used for the 7% and 8% yttria-stabilized ZrO2 series. The tests of microhardness and fracture toughness of the materials were performed by the indentation method. It was found that both the yttria percentage and the sintering temperature affect the mechanical behaviour of the ceramics. The maximum transformation toughening effect during indentation was revealed for the ceramic ZrO2-6 mol% Y2O3. Using the phase balance analysis, it was found that such toughening of ceramics is related to corresponding levels of fracture toughness.
