文摘
- •
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.
