摘要:

利用材料挤出成形设备制备不同过程参数(不同层厚、粉末含量或填充角度)的静力学实验生坯试件,以验证自制氧化锆粉末/聚合物复合丝材的可成形性;然后对生坯试件进行脱脂和烧结处理,以获得致密化的纯陶瓷材料烧结试件;最后针对烧结试件分别进行物理属性及静力学性能的实验研究,探究不同过程参数对试件静力学性能的影响规律。结果表明,两步式脱脂效果良好,试件脱脂率达99%,密度达6.02 g/cm3;增大陶瓷粉末含量会显著降低烧结试件的收缩率;层厚对试件的压缩和弯曲性能影响显著,当层厚增至0.30 mm时,试件的抗压与抗弯强度分别降至213.40 MPa及293.12 MPa;当填充角度由0°增至90°时,试件的抗弯强度由456.01 MPa降至120.08 MPa。

Abstract:

The static mechanics experimental green specimens built with different processing parameters (i.e. layer thickness, ceramic powder content or filling angle) were formed using the material extrusion (ME) equipment to verify the formability of the self-made zirconia powder/polymer composite filament.The green specimens were then subjected to degreasing and sintering processes to obtain densified pure ceramic sintered specimens. Experimental studies on the physical and static mechanics properties of the sintered specimens were conducted respectively, exploring the influencing laws of different processing parameters on the static mechanics properties of the specimens. The results show that the two-step degreasing method has a good effectiveness, with the degreasing rate and density being 99% and 6.02 g/cm3, respectively. Increasing the content of ceramic powder may significantly reduce the dimensional shrinkage of sintered specimens. The layer thickness has a significant influence on their compression and bending properties, when the layer thickness increases to 0.3 mm, the compressive and bending strengths are dropped to 213.40 and 293.12 MPa, respectively.When the filling angle increases from 0° to 90°, the bending strength is decreased from 456.01 to 120.08 MPa.
