Effect of Titania (TiO2) Addition to Zirconia Toughened Alumina (ZTA) Phases, Hardness and Microstructure

Ceramic composites consist of zirconia toughened alumina (ZTA) with TiO2 as additive was fabricated via solid state sintering route. Numerous studies have indicated that TiO2 can be used as sintering additives for Al2O3 and the ability of microstructural control introduce by TIO2. The Vickers har...
