Why ZTA?  Parts and components made out of Zirconia Toughened Alumina (ZTA) are better in strength & toughness over alpha alumina engineered ceramics. The increased strength and toughness in ZTA is attributed to the stress induced transformation toughening mechanism which is created due to addition of optimized amounts of nano crystalline zirconia particles dispersed though-out the alumina ceramic body.The zirconia composition in ZTA is around 20%. When any crack grows through the ceramic, the crystal structure of the zirconia particles in the region of the crack changes from the metastable tetragonal phase to the stable monoclinic phase. The change increases the volume of the particles by about 3-4% and generates compressive stresses in the alumina matrix. Stresses in turn close the crack and act as an energy barrier to further crack growth. The addition of zirconia to the alumina matrix increases fracture toughness by two times and can be improved by as high as four times, while strength is more than doubled.
Applications:  ZTA components are expensive when compared with alpha alumina but far better component life and performance prove them cost effective solutions for demanding tough application conditions Major Applications include: Due to Excellent mechanical strength, Wear resistance ,High temperature stability ,Corrosion resistance properties ZTA finds applications in Bearing components (balls, rollers and raceways),Bushings ,Die and cutting tool inserts (replacing carbide and metal tool inserts) ,Valve seats , Pump components……
