摘要/Abstract

摘要： 目的：研制新型口腔修复用纳米复合全瓷材料并探讨其力学性能。方法：将纳米ZrO₂(3Y)粉体以不同体积百分比加入微米级Al₂O₃粉体中,测试不同纳米粉含量对试样力学性能的影响。结果：添加10%（V/V）ZrO₂(3Y)粉体时试样力学性能最佳，其弯曲强度和断裂韧性分别为(424.43±30.30)MPa和(4.31±0.30)MPa m^1/2。结论：添加10%（V/V）ZrO₂(3Y)纳米粉的纳米复合陶瓷, 其力学性能可以满足口腔修复需要,添加过量纳米粉反而使试样力学性能降低。

Abstract: Objective To study the new kind of nano-ceramic composite for prosthodontics and its mechanical property. Methods The different volume fractions of Zirconia nano-powder were added into micrometer Alumina powder and the mechanical properties of the samples were tested. Results The sample with 10%（V/V）ZrO₂(3Y) nano powder had the best mechanical properties，the flexural strength and fructure toughness were (424.43±30.30)MPa and(4.31±0.30)MPa m^1/2,respectively. Conclusion The mechanical property of nano-ceramic composite with 10%（V/V）ZrO₂(3Y) nano powder could fit the demand of prothodontics,excessive content of nano-powder decrease the samples′ properties on the contrary.
