Description

一种高强度复合陶瓷刀具及其制备方法
技术领域
本发明属于陶瓷刀具制备领域，具体地说是涉及一种高强度复合陶瓷刀具及其制备方法。
背景技术
陶瓷刀使用精密陶瓷高压研制而成，故称陶瓷刀。
随着新技术革命的发展，要求不断提高切削加工生产率和降低生产成本，特别是数控机床的发展，要求开发比硬质合金刀具切速更高、更耐磨的新型刀具。日前各种高强度、高硬度、耐腐蚀、耐磨和耐高温的难以切削的新材料日益增多。硬质合金刀具对其中不少新材料的加工难以胜任。另一方面，矿产资源正日益减少，价格上涨，导致硬质合金刀具生产成本增加。
复合陶瓷刀具有硬度高、耐腐蚀性强、化学稳定性好、高耐磨性等特点，外型美观、精致，刃口锋利无比，能切割钢铁等物质，能削出如纸一样薄的肉片；其耐磨性是金属刀的60倍。在现代工业和日用厨具中被广泛使用。
但现有复合陶瓷刀具的主要缺点就是抗弯强度及断裂性能差。
发明内容
为解决上述技术问题，本发明提供一种高强度复合陶瓷刀具及其制备方法。以解决现有复合陶瓷刀具韧性及抗断裂性能差的问题。
为达到上述目的，本发明所采取的技术方案为：
一种高强度复合陶瓷刀具，由重量份数计，主要包括以下原料：氧化锆60-75份、氧化钪4-8份、二硼化铬1-5份、硅藻土3-7份、氧化镁1-7份、硼砂2-4份、二硅化钽0.5-3份、氧化钛0.12-0.5份、硝酸镧0.02-0.10份、氯化铈0.01-0.5份、分散剂2-5份、粘结剂0.2-5份、氢氧化四甲胺0.2-0.5份、二乙醇胺13-17份和氨水23-28份。
优选地，在本发明的较佳实施例中，所述原料还包括2-6份氧化钇和3-6份氧化铝；由四方氧化锆作基体，加入氧化钇作稳定剂，氧化铝的加入也有利于防止及减少氧化锆相转变时发生的体积收缩，能对氧化钇稳定氧化锆的四方晶相起协同效应，提高其稳定效果，同时也能提高陶瓷刀具的烧结的致密度，提高其抗弯折性能。
优选地，在本发明的较佳实施例中，所述分散剂为柠檬酸钠、乙二胺四乙酸钠、羟甲基纤维素或聚乙烯醇中的任意一种；分散剂能有效地防止了粒子的团聚，原料各组分可均匀分散于介质中，对提高陶瓷制品的抗断裂性能起着至关重要的作用。
优选地，在本发明的较佳实施例中，所述粘结剂由硫酸镁、磷酸、硼酸组成，所述硫酸镁、磷酸、硼酸的重量比为7-9:3-1:1-10。
本发明提供了一种高强度复合陶瓷刀具的制备方法，包括以下步骤：
(1)将所述氧化锆、所述氧化钇、所述氧化铝和所述分散剂加入所述二乙醇胺中，在45-50℃搅拌15-20min，得到凝胶；
(2)将所述凝胶置于所述氨水中浸泡后，在90-100℃烘干1-2h，再在920-950℃下煅烧处理5-9h，得到稳定的氧化锆粉体；
(3)按重量比称取所述氧化钪、所述二硼化铬、所述硅藻土、所述氧化镁、所述硼砂、所述二硅化钽、所述氧化钛、所述硝酸镧和所述氯化铈，将各组分加入足量去离子水中，搅拌混合；
