Treatment method for enhancing porosity of outer surface of porous zirconia ceramic
A treatment method for enhancing the porosity of the outer surface of porous zirconia ceramic comprises the following steps: preparing an etchant solution which is an acidic solution or an alkaline solution; heating the prepared corrosion solution in a water bath to 60-70 DEG C; the zirconia ceramic blank subjected to direct-writing printing is immersed in a corrosion solution heated in a water bath, stirring corrosion is conducted for 5-200 min, and direct-writing printing ink adopted for direct-writing printing comprises a pore forming agent; the corroded sample piece is taken out of the corrosion solution and then cleaned with deionized water; the cleaned sample piece is dried; and putting the dried sample piece into a sintering furnace, sintering in an air atmosphere, taking out the sample piece after the temperature is naturally reduced to room temperature, and completing sintering to obtain a porous ceramic product. According to the method, a multi-scale multi-structure pore structure can be formed on the outer surface of the zirconia ceramic, the cost is low, the material removal amount is controllable, the whole body is uniform, the preservation time is long, and the material system is stable.
一种增强多孔氧化锆陶瓷外表面孔隙率的处理方法，包括以下步骤：配制腐蚀溶液，所述腐蚀溶液为酸性溶液或碱性溶液；将配制得到的腐蚀溶液进行水浴加热至60℃‑70℃；将直写打印的氧化锆陶瓷胚体浸入到水浴加热后的腐蚀溶液，搅拌腐蚀5min‑200min，其中，直写打印采用的直写打印墨水包括造孔剂；将腐蚀后的样件从腐蚀溶液中取出后用去离子水进行清洗；将清洗后的样件进行干燥；将干燥后的样件放入到烧结炉内，在空气氛围中进行烧结，待温度自然降至室温后，取出样件，完成烧结，得到多孔陶瓷产品。本发明能在氧化锆陶瓷外表面形成多尺度多结构的孔隙结构，成本低，材料去除量可控、整体均一，且保存时间久，材料体系稳定。
