一种陶瓷插芯的制备方法
摘要：
本发明提供了一种陶瓷插芯的制备方法，包括：将纳米金刚石、二硼化钛、氧化铝、氧化钐、氧化镝、氧化铕和氧化锆混合，预烧后加入石蜡，球磨混合，过筛后得到部分稳定氧化锆粉末；将所述部分稳定氧化锆粉末与己二酸二辛酸、乙烯-醋酸乙烯共聚物、硬脂酸、聚苯乙烯、聚乙二醇混合，搅拌，密炼，冷却，得到胶状物质；将所述胶状物质压片，粉碎，注射成型后得到毛坯料；将所述毛坯料浸泡在汽油中，然后依次进行热脱脂处理和烧结处理，得到陶瓷插芯。与现有技术相比，本发明采用的纳米金刚石能提高陶瓷插芯的耐磨性和抗老化性能，而二硼化钛提高硬度、抗氧化性能和抗老化性能。因此，本发明制备的陶瓷插芯具有良好的耐磨性和抗老化性能。
摘要（英）：

The invention provides a ceramic insertion core preparation method which comprises the steps: mixing nano diamond, titanium diboride, aluminum oxide, samarium oxide, dysprosium oxide, europium oxide and zirconium oxide, adding paraffin after sintering, ball milling and mixing and sieving to obtain partially stabilized zirconium oxide powder; mixing the partially stabilized zirconium oxide powder with hexanedioic di-caprylate, ethylene-vinyl acetate copolymer, stearic acid, polystyrene and polyethylene glycol, stirring, smelting and cooling to obtain gelatinoid; sheeting, smashing and injectionmolding the gelatinoid to obtain a rough material; soaking the rough material in to gasoline and then sequentially performing thermal ungreasing treatment and sintering treatment to obtain a ceramicinsertion core. Compared with the prior art, the nano diamond utilized by the ceramic ferrule disclosed by the invention can improve wear resistance and ageing resistance of the ceramic ferrule, and the titanium diboride can improve hardness, oxidation resistance and ageing resistance; thus, the prepared ceramic insertion core disclosed by the invention has good wear resistance and ageing resistance.
