A homemade 1-inch 10.7 mol% yttria-stabilized zirconia (10.7 YSZ) target was used in the experiment. The YSZ target was made by ball-milling mixed powers (zirconia and yttria) of yttria mole fractions of 0.107 for 24 h. After the ball-milling process, the powers were pressed into disks and sintered at 1500 °C for 4 h [31].

Ideal for applications that must resist bending and wear as well as carry heavy loads, these rods and discs are often used for sleeve bearings and shafts instead of metal. Added yttria gives this material more strength and lowers the chances of cracking from impact compared to standard zirconia, alumina, and silicon nitride ceramic. If cracks do occur, they will not spread, …

As far as we know, the investigations on the thermal properties have been focused on 3-4YPSZ. However, the thermal properties for the fully stabilized zirconia ce- ramics doped with high content of yttria have been studied insufficiently. Particularly, for the cases temperature is higher than 1 000 ºC.
The potential for additional toughening contributions from microcracking and ferroelastic toughening is briefly addressed and the coupling of toughening mechanisms is also discussed. Finally, a perspective on the future development of Y-TZP-based high toughness materials is given.
