Description
技术领域
本发明涉及陶瓷材料合成技术领域,具体涉及一种预应力氧化铝陶瓷复合材料及其制备方法。
背景技术
氧化铝陶瓷是以α-Al2O3为主晶相的结构陶瓷,由于其具有高强度、高硬度、耐高温、良好的电绝缘性能,特别是具有优异的化学稳定性和抗氧化性,并且原料来源广泛、价格低廉,在电子、航空、机械、化工、建筑等工程领域已得到了较广泛的应用。
但是氧化铝陶瓷材料存在热膨胀系数高,抗热震性能、导热性不及非氧化物等问题,并且作为一种典型的脆性材料抗压却不抗拉,破坏时候断裂应变小,容易发生突发性脆性断裂。因此简易的实现氧化铝的增强增韧、提高其可靠性是实现氧化铝再度发展的决定性因素。
目前,提高氧化铝陶瓷强度的方法有改善烧结工艺、引入颗粒增强相(颗粒、纤维)、仿生层状结构、表面处理等,但是这些方法主要应用在军工、航天等重要领域,也会受到成本以及形状尺寸的限制。
发明内容
为解决现有技术中存在的问题,本发明提供一种预应力氧化铝陶瓷复合材料及其制备方法。本发明通过在未烧结的氧化铝表面制备石英-氧化铝涂层,共同烧结致密后涂层在降温过程中将形成残余压应力,从而解决氧化铝陶瓷力学强度与韧性的较低难题,同时可以提高氧化铝的高温强度和耐腐蚀性。
为解决上述技术问题,本发明提供技术方案如下:
一方面,本发明提供一种预应力氧化铝陶瓷复合材料,所述复合材料以氧化铝为基体,上下表面均设置有厚度为20-150μm的莫来石涂层,且所述基体与涂层的厚度比大于10。
进一步的,所述涂层为石英和氧化铝的混合物涂敷在基体表面后,与基体共同烧结后形成的。
优选的,所述混合物中石英的质量分数为5-30%,氧化铝质量分数为70-95%。
另一方面,本发明还提供一种预应力氧化铝陶瓷复合材料的制备方法,包括:
(1)氧化铝坯体的制备:坯体采用干压成型,50-70MPa干压成型,再150-300MPa冷等静压成型,经过800-1100℃预烧排除坯体有机物;
(2)涂层浆料的制备:将涂层粉体、分散剂、粘结剂混合在酒精或者水中,高速球磨分散成涂层浆料;
(3)坯体上制备涂层:将涂层浆料均匀的涂在氧化铝预烧过的坯体上,重复5-10次,最后阴干2h;
(4)预应力复合体的烧结:升温至500℃-800℃,保温0.5h-1h;然后以5-20℃/min升至1500℃-1700℃保温1-2小时随炉冷却即可。
进一步的,所述步骤(2)中,涂层粉体为石英和氧化铝混合物,粒径D50小于1μm,以提高涂层粉体的烧结活性。石英的质量含量分数为5-30%,氧化铝为95-70%。
进一步的,所述粘结剂为聚乙烯醇缩丁醛酯、聚乙烯醇、异丁烯马来酸酐共聚物(ISOBAM)中的一种或多种。
进一步的,所述分散剂为蓖麻油、鱼油、聚丙烯酸、柠檬酸钠的一种或多种。
进一步的,所述粘结剂用量为涂层粉体质量的1~10%;所述分散剂用量为涂层粉体质量的0.1~1%。
进一步的,所述球磨速度200~500转/min,时间2h以上。
莫来石作为Al2O3-SiO2二元体系中较为稳定化合物,具有低热导率、较高的高温强度、良好的抗热冲击性能、热膨胀系数低、抗氧化、抗化学腐蚀性、同时具有良好的高温稳定性和抗热震性。因此通过在未烧结氧化铝表面制备石英-氧化铝涂层不仅可以在高温下形成莫来石,还能在降温过程形成压缩应力,从而达到大幅提高氧化铝强度的目的,或者称为(钢化陶瓷)。
与现有技术相比,本发明具有以下有益效果:
本发明提供一种在氧化铝表面制备莫来石预应力涂层的方法,可以利用莫来石的低膨胀系数,在烧结后期降温过程中基体收缩大,涂层收缩小,而两者通过强界面相互牵拉,因此涂层中会形成残余压缩应力(类似钢化玻璃),赋予氧化铝更好的高温稳定性和抗热震性能,同时莫来石较低的介电常数也能降低氧化铝的介电常数,使得更有利于应用在电子封装领域。如图1所示。
附图说明
图1为本发明实施例1方法制备的材料的结构示意图和其截面的应力示意图;
图2为本发明实施例1方法制备的材料的SEM图片。
具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
实施例及对比例中所用试剂及材料,如无特殊说明,均可经过商业途径得到。
本发明提供一种预应力氧化铝陶瓷复合材料及其制备方法,具体实施例如下。
实施例1

(2)涂层浆料的制备:采用酒精为溶剂,将掺量为15wt%的石英(SiO2)与85wt%氧化铝(D50=400nm的Al2O3)混合,加入粉体质量5%的粘结剂PVB(聚乙烯醇缩丁醛)和粉体质量0.5%分散剂蓖麻油,转移至行星球磨机中(YXQM-1L,MITR,China)球磨分散5h,球料比为10:1,转速300r/min。
(3)坯体上制备涂层:用细毛刷蘸取少量分散后的涂层浆料,在氧化铝坯体上下表面均匀刷涂,上下刷涂次数各5次,刷涂后阴干2小时以上,再放入烧结炉中烧结。
(4)预应力复合体的烧结:升温至500℃,保温0.5h;然后以5℃/min升至1600℃保温2小时随炉冷却即可
由图2可知,本发明制备的涂层均匀的附着在氧化铝基体陶瓷上,并且涂层与基体结合紧密,无裂纹、界面滑移等缺陷。
实施例2
本实施例中涂层原料石英:氧化铝=5:95,其余条件与实施例1相同。

对利用上述实施例1-2和对比例1-5的方法制备的材料进行弯曲强度性能测试,测试方法参照《GBT6569-2006-精细陶瓷弯曲强度试验方法》,结果如表1所示。
表1氧化铝和预应力氧化铝陶瓷弯曲强度
由表1可知,本发明制备的预应力氧化铝陶瓷复合材料相较于氧化铝陶瓷基体,其弯曲强度提高18-37%。
调整粘结剂的种类为聚乙烯醇、异丁烯马来酸酐共聚物中的一种或几种,或者是调整分散剂的种类为鱼油、聚丙烯酸、柠檬酸钠的一种或多种,制备的复合材料的弯曲强度均提高15%以上。
在限定范围内,调整本发明中各步骤工艺参数,制备的复合材料的性能与前述实施例一致,在此不再赘述。
综上可知,本发明利用石英-氧化铝在氧化铝陶瓷表面制备低膨胀系数的莫来石涂层,降温过程中基体收缩大,涂层收缩小,在涂层中会形成残余压缩应力,从而大幅提高氧化铝强度的目的。
以上是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以作出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
