Gradient zirconium oxide ceramic cutter material and preparation method thereof
The invention belongs to the technical field of ceramic cutters, and discloses a gradient zirconia ceramic cutter material and a preparation method thereof. The gradient zirconium oxide ceramic cuttermaterial is prepared by the following steps: molding yttrium-stabilized zirconium oxide powder through a biscuit, and presintering in air at 800-1200 DEG C to obtain a pre-sintered blank; and machining the pre-sintered blank into a blank, drying the obtained cutter blank, soaking the dried cutter blank in a yttrium salt solution, an alkali solution, an oxalic acid solution and flowing deionized water in sequence, performing drying to obtain an infiltrated blank, and sintering the infiltrated blank in air at 1350-1500 DEG C to obtain the cutter material. The cutter material disclosed by the invention has the excellent characteristics of hard surface and tough core structure, good biocompatibility and the like; and by means of near-net forming and in-situ permeation synthesis, large-batch production can be achieved, the production efficiency is high, the product yield is high, the cost is low, and more reliable stability and longer service life can be obtained compared with a homogeneous zirconium oxide tool when the method is used for high-speed machining.
本发明属于陶瓷刀具技术领域，公开了一种梯度氧化锆陶瓷刀具材料及其制备方法。所述梯度氧化锆陶瓷刀具材料是先将钇稳定氧化锆粉体经素坯成型，在空气中800～1200℃预烧，制得预烧坯；再将预烧坯经机械加工成毛坯，所得刀具坯干燥后依次置于钇盐溶液、碱液、草酸溶液、流动的去离子水中浸泡，干燥后制得浸渗坯，将浸渗坯在空气中1350～1500℃烧结制得。本发明的刀具材料具有表硬芯韧的结构，生物亲和性好等优异特点；通过近净成型与原位渗透合成方法，可大批量生产，生产效率高，产品良率高，成本低，用于高速加工可获得比均质氧化锆刀具更可靠的稳定性以及更长的使用寿命。
