这项研究考察了等离子喷涂锆石的烧结率和烧结量。时间(1-24小时)、温度暴露(1038-1510°C)和二氧化硅杂质含量(0.2%-4.0%)。机械性能的变化(高达3.5倍的原始强度和4倍的原始模数)被证明与烧结有关。在低至1100℃的温度下，烧结对喷雾材料的力学性能有显著的影响。讨论了杂质水平、显微组织形态和稳定剂浓度的影响。
This study examines the rate and magnitude of sintering in plasma-sprayed zirconiavs. time (1 – 24 h), temperature exposure (1038 – 1510 °C) and silica impurity level (0.2% – 4.0%). Mechanical property changes (up to 3.5 times the original strength and four times the original modulus) are shown to be associated with sintering. Significant effects of sintering on the mechanical properties of the sprayed material are seen at temperatures as low as 1100 °C. The discussion includes effects of impurity level, microstructural morphology and stabilizer concentration.
