| 英文摘要 | The phase relationship and microstructural characteristics were systematically studied for co-stabilized ZrO2 ceramics with Nd2O3-Y2O3 additives coated onto starting powder. Polishing induced surface morphological changes by tetragonal-to-monoclinic transformation were observed by SEM. EDS analysis revealed a bi-modal distribution of the stabilizers correspondingly to smaller transformable tetragonal grains and larger non-transformable cubic grains. The correlation of co-stabilizer concentrations with the dual-phase microstructures leads to a probable two-stage sintering enabled by transient liquid-phase started from coating. Small t-ZrO2 grains inherited the starting nanopowder to take less stabilizers via diffusion, and larger c-ZrO2 grains incorporate directly stabilizers during growth from liquid-phase accumulated more stabilizers. The transformability of t-ZrO2 grains is influenced by neighboring c-ZrO2 grains when a compressive stress on the former is sufficiently large from the latter in larger size and high modulus, which could be regulated by the two-stage process to optimize the dual-phase microstructure. |
