Complexity of the relationships between the sintering-temperature-dependent grain size, airborne-particle abrasion, ageing and strength of 3Y-TZP ceramics

Highlights • Sintering temperature affects the grain size, transformability and strength of 3Y-TZP. • The high-temperature-sintered, coarse-grained 3Y-TZP experiences a higher surface strengthening than the low-temperature-sintered, fine-grained 3Y-TZP. • Ageing resistance after airborne-particle ab...

Zusammenfassung:	Highlights • Sintering temperature affects the grain size, transformability and strength of 3Y-TZP. • The high-temperature-sintered, coarse-grained 3Y-TZP experiences a higher surface strengthening than the low-temperature-sintered, fine-grained 3Y-TZP. • Ageing resistance after airborne-particle abrasion is greater in the high-temperature-sintered, coarse-grained 3Y-TZP.
