Description

抗热震复相陶瓷材料及基于该材料的陶瓷漏嘴的制备
技术领域
本发明涉及一种陶瓷材料，尤其是涉及抗热震复相陶瓷材料及基于该材料的陶瓷漏嘴的制备。
背景技术
高温合金粉末是现代金属增材制造复杂部件的重要原料，陶瓷漏嘴是雾化法制备高温合金粉末装置的关键部件之一。传统的陶瓷漏嘴，在内置1500℃熔融金属，外侧高速气流喷吹的极端环境下，很容易产生裂纹或“炸裂”，或由于耐高温、耐金属熔体侵蚀差，造成雾化制成的高温合金粉末成球性差，并可引起熔融金属从裂缝快速流出的危险。
中国专利CN106242565A公开了一种耐磨ZrO2-Al2O3复相陶瓷颗粒及其制备方法和应用，属于陶瓷复合材料制备技术领域，耐磨ZrO2-Al2O3复相陶瓷颗粒组成成分的质量分数为：10％～90％的稳定ZrO2以及10％～90％的Al2O3；采用电熔融、水冷制备得表面粗糙、粒径为0.5～7mm的高耐磨性ZrO2-Al2O3复相陶瓷颗粒，生产效率高，性能稳定，并将耐磨ZrO2-Al2O3复相陶瓷颗粒应用于制备钢铁基复合材料的增强体，能显著增强复合材料耐磨性。但是该专利中ZrO2-Al2O3复相陶瓷颗粒主要改善了材料耐磨性能，没有涉及改善陶瓷材料的抗热震性能；需要在1800℃以上电熔融、水冷制备，其制备过程能耗高；并且仅涉及0.5～7mm的ZrO2-Al2O3耐磨陶瓷颗粒，没有涉及以该材料为基体制备抗热震块体。
中国专利CN101209925B公开了一种提高氧化铝/氧化钛复相精细陶瓷材料弯曲强度和断裂韧性的方法，解决了现有Al2O3/TiO2复相陶瓷的弯曲强度、断裂韧性和硬度性能低的问题。该方法的步骤是：在球磨机中用去离子水做介质将精细氧化铝和氧化钛纳米粉体、改性剂、粘结剂聚乙烯醇混合成均匀浆料；然后喷雾干燥再造粒；随后对所得粉体进行热处理；经过热处理的粉体进行预压成型；坯料进行冷等静压成型后烧结。上述方法实现了精细陶瓷材料制备过程中陶瓷的低温快速烧结，明显降低了生产的成本，同时提高了产品的弯曲强度、断裂韧性和硬度。该专利主要改善了现有Al2O3/TiO2复相陶瓷的弯曲强度、断裂韧性和硬度性能低的问题，并有低温快速烧结的优点，同时没有涉及改善陶瓷材料的抗热震性能和高温抗侵蚀性能，特别是在1000～1500℃烧结的材料，耐高温性能不够，不适用于高温合金雾化制粉漏嘴；并且主要原料采用纳米氧化铝和纳米氧化钛粉体，成本较高。
发明内容
本发明的目的就是为了克服上述现有技术存在的缺陷而提供一种抗热震复相陶瓷材料及基于该材料的陶瓷漏嘴的制备。
本发明的目的可以通过以下技术方案来实现：
一种抗热震复相陶瓷材料，由含下述质量分数的原料制成：Al2O3 69.01％～76.00％、ZrO2 17.01％～24.13％、SiO2 5.29％～5.97％、MgO 0.05％～0.89％或Y2O30.05％～1.33％、TiO2 0.05％～0.19％、结合剂0.5％～1.5％。所述的结合剂为PVA、甲基纤维素或糊精中的一种或几种。所述的结合剂为PVA、甲基纤维素或糊精中的一种或几种。
原料中的Al2O3一部分形成耐高温的刚玉相基质相，其余部分与原料中含有的SiO2形成材料的莫来石相，低于所述的加入量，将会造成材料的耐高温性和机械强度下降；Al2O3加入量过多，复合材料中的刚玉相/莫来石比例过高，将会造成材料的抗热震性下降。
原料中加入的17.01％～24.13％ZrO2与材料中的氧化铝形成复合增韧基质材料，起提高材料的机械性能和抗热震性的作用，并可提高复合材料的高温抗侵蚀性能。
原料中加入的少量的MgO或Y2O3、TiO2主要是起烧结助剂和氧化锆稳定剂的作用。
进一步地，所述的抗热震复相陶瓷材料含有α－氧化铝相(刚玉相)、氧化锆相和莫来石相。氧化锆相和刚玉相在复相材料中为基质相，具有耐高温、耐腐蚀的特点。氧化锆相均匀分布在刚玉基质相中，在烧结过程中，随温度冷却，四方相氧化锆部分或全部转变成单斜氧化锆，并伴随一定的体积膨胀，在Al2O3和ZrO2晶界处产生压应力，起到复合增韧的作用。莫来石是Al2O3和SiO2在高温下生成的矿物，晶体为细针状。膨胀系数(25～1000℃)5.3×10－6/℃，具有良好的抗热震性，在本发明的材料中，针状莫来石穿插分布在基质相之间，进一步提高了本发明的复相陶瓷漏嘴的抗热震性能。
所述的抗热震复相陶瓷材料的制备方法，包括以下步骤：
1)将含下述质量分数的原料：Al2O3 69.01％～76.00％、ZrO2 17.01％～24.13％、SiO2 5.29％～5.97％、MgO 0.05％～0.89％或Y2O3 0.05％～1.33％、TiO2 0.05％～0.19％、结合剂0.5％～1.5％加水混合，加水量占原料与水总重量的4-6％；
2)将上述混合成分经90～220MPa等静压成型，在1630～1680℃温度范围高温烧结，随炉自然降温，制得抗热震复相陶瓷材料。
本发明还提供基于所述抗热震复相陶瓷材料的陶瓷漏嘴。
所述的陶瓷漏嘴的制备方法，包括以下步骤：
1)将含下述质量分数的原料：Al2O3 69.01％～76.00％、ZrO2 17.01％～24.13％、SiO2 5.29％～5.97％、MgO 0.05％～0.89％或Y2O3 0.05％～1.33％、TiO2 0.05％～0.19％、结合剂0.5％～1.5％加水混合，加水量占原料与水总重量的4-6％；
2)将上述混合成分经90～220MPa等静压成型为漏嘴，在1630～1680℃温度范围高温烧结，制得抗热震复相陶瓷漏嘴。
所述的陶瓷漏嘴主要用于高温合金雾化制粉。
本发明通过对原料与原料配比进行优化选择，并在原料选择的基础上，优化高温烧结的工艺，使得材料含有α－氧化铝相、氧化锆相和莫来石相。本发明中高温烧结的温度与时间对于材料的性能有重要影响，如果在其他温度烧结会产生不良的烧成结果，温度过低或保温时间过短，会产生欠烧，材料的机械性能降低；温度过高或保温时间过长，会产生烧结变形。
所述的抗热震复相陶瓷材料含有α－氧化铝相、氧化锆相和莫来石相，具有耐高温、耐熔融金属侵蚀，以及抗热震性能优越等特点，尤其适用于制成抗热震复相陶瓷漏嘴，因此，本发明提供了一种基于抗热震复相陶瓷材料的陶瓷漏嘴，克服了传统陶瓷漏嘴的缺点，所述的抗热震复相陶瓷漏嘴用于高温合金雾化制粉。
与现有技术相比，本发明的有益效果是：提供的抗热震复相陶瓷材料，由于含有相当数量的较低热膨胀系数莫来石相和抗侵蚀性能好、强度高的氧化锆，具有耐高温、耐熔融金属侵蚀，以及抗热震性能优越等特点；克服了传统的陶瓷漏嘴缺点，适用用于高温合金雾化制粉。

以上实施例表明本发明的复合陶瓷漏嘴性能稳定，抗热震性好，耐火度高，雾化制备的高温合金粉末球形度好，纯度高，适用于3D打印。具有耐高温、耐熔融金属侵蚀，以及抗热震性能优越等特点；克服了传统的陶瓷漏嘴的缺点，适合用于高温合金雾化制粉，有广阔的应用前景。
上述的对实施例的描述是为便于该技术领域的普通技术人员能理解和使用发明。熟悉本领域技术的人员显然可以容易地对这些实施例做出各种修改，并把在此说明的一般原理应用到其他实施例中而不必经过创造性的劳动。因此，本发明不限于上述实施例，本领域技术人员根据本发明的揭示，不脱离本发明范畴所做出的改进和修改都应该在本发明的保护范围之内。
