中文摘要
本研究的目的是通过加速老化试验比较新型掺硅Y-TZP材料与常规Y-TZP材料的降解情况。加速试验结果表明,经过50小时的老化后,常规Y-TZP样品的表面损伤程度降低了50% ~ 60%,而掺硅Y-TZP样品的表面损伤程度仅降低了不到20%。常规Y-TZP样品的单斜晶含量大幅增加至62.7%,而掺杂二氧化硅的Y-TZP样品在时效5小时后的单斜晶含量为18.9%。
英文摘要
The aim of this study was to compare the degradation of a new silica doped Y-TZP material with that of conventional Y-TZP by using accelerated aging tests. The results of the accelerated tests revealed that after 50 hours of aging, the conventional Y-TZP samples had damaged surfaces that were weakened by 50 to 60%, while the silica-doped Y-TZP samples were only weakened by less than 20%. The monoclinic content of the conventional Y-TZP samples increased substantially to 62.7%, however, that of silica-doped Y-TZP samples was 18.9% after 5 hours of aging.
