摘要: 彩色氧化锆陶瓷因具有可调控的色彩、较好的机械加工性和较强的稳定性,可广泛应用于手机背板、高端装饰材料等高科技领域。本研究制备了三种不同Co3O4含量,总固含量为55%(体积分数)的蓝色氧化锆陶瓷膏料,并成功将其用于立体光刻(SLA)光聚合打印。结果表明,与未着色的陶瓷样品相比,添加少量Co3O4会使陶瓷样品的抗弯强度略微提升。烧结后的平均晶粒尺寸随着Co3O4含量的增加而增大,陶瓷样品中的单斜相结构逐渐增多。并且对蓝色氧化锆陶瓷样品的致色机理进行了研究,随着Co3O4含量的增加,陶瓷样品在可蓝光范围(435~490 nm)内的反射率出现明显下降,当Co3O4含量为1.0%(质量分数)时,所获陶瓷样品的机械性能和光学性能最佳。陶瓷样品的抗弯强度和维氏硬度,明显优于同类研究的结果。本研究实现了使用蓝色陶瓷材料打印整体式可移动部件,该部件具有高精度和优越性能,为高端装饰材料领域打印高强度结构提供了可能。

Abstract: Colored zirconia ceramics can be widely used in high-tech fields such as mobile phone backplanes and high-end decorative materials due to their adjustable color, good mechanical processing and strong stability. In this study, three blue zirconia ceramic pastes with different Co3O4 content and a total solid content of 55% (volume fraction) were prepared and successfully used for stereolithography (SLA) photopolymerization printing. The results show that the addition of a small amount of Co3O4 slightly improves the flexural strength of the ceramic samples compared with the uncolored samples. The average grain size after sintering increases with the increase of Co3O4 content, and the monoclinic phase structure in the ceramic samples gradually increases. And the chromogenic mechanism of the blue zirconia ceramic samples is investigated, with the increase of Co3O4 content, the reflectance of the ceramic samples in the blua light range (435~490 nm) appeares to be significantly decreased. When the Co3O4 content is 1.0% (mass fraction), the mechanical and optical properties of the obtained samples are the best. The flexural strength and Vickers hardness of the ceramic samples are significantly better than those obtain in previous studies. This study has realized the use of blue ceramic materials to print monolithic movable parts, and this parts achieve high precision and superior performance, providing the possibility of printing high-strength structures in the field of high-end decorative materials.
