Description

一种近零膨胀Al-ZrW2O8复合材料的制备方法
技术领域
本发明涉及精密仪器领域低膨胀系数材料的制备方法，特别涉及在宽的温度范围内具有近零膨胀系数的Al-ZrW2O8材料的制备方法。
背景技术
近零膨胀材料是支撑精密器件结构尺寸稳定性、低环境敏感性及冷热冲击情况下结构和功能方面稳定性的重要需求，是卫星通讯、光学***、电子封装、精密仪器和信息安全等领域的关键材料。
因瓦合金(Invar)是一种在室温附近具有极低热膨胀系数的合金(约为1.5 ×10- 6K-1),制造工艺成熟、可靠，广泛应用于长度标尺、大地测量基线尺、微波技术、液态气体容器、谐振腔、航天遥感器、精密激光、光学测量***、波导管结构件、天文望远镜支撑***以及光学透镜等科学仪器中。然而，因瓦合金存在密度大(密度8.1g/cm3)、低膨胀区温度范围窄(-20～20℃)、热导率低 (仅为45钢导热系数的1/4～1/3)，难以满足现代航空航天和光学通讯领域的发展需求。
ZrW2O8(钨酸锆)是一种各向同性的负膨胀材料，在-270～770℃温度区间内展现负膨胀效应,负膨胀系数达到-8.9×10-6K-1，与铝合金匹配可获得一种密度小、热导率高、在更宽温度范围内具有近零热膨胀系数的复合材料。然而，已经制备出的Al-ZrW2O8材料热膨胀系数往往显著大于按二组元匹配得到的理论计算值、也不能获得近零的膨胀系数。
已经制备出的Al-ZrW2O8材料不能获得近零热膨胀系数的原因在于ZrW2O8在材料中呈弥散的颗粒状分布，虽然其单独颗粒能够在温度变化过程中为周围的铝基体提供变形空间、降低整个材料的变形量，但由于ZrW2O8颗粒之间不能彼此协调发挥整体约束作用，铝合金基体仍然能够不受约束地向周围的3D空间变形，使材料的热膨胀系数显著大于根据Al和ZrW2O8二组元各自热膨胀系数理论计算得出的结果，更无法获得近零的热膨胀系数值。
如果能够改变Al-ZrW2O8材料中ZrW2O8相的分散分布状态，将ZrW2O8相由离散分布改变为连续骨架状分布，则可以使ZrW2O8不仅在微观上为铝相提供反向变形空间，在宏观上也能够发挥整体约束作用，使ZrW2O8以骨架形式完全承担铝合金基体由于温度变化产生的内部应力和抵消其变形程度，在整体结构上约束Al合金相的反向变形，Al相和ZrW2O8相二者的相互配合制造出相当于理论计算值的热膨胀系数，从而可由成份设计精确制造出近零膨胀系数的Al-ZrW2O8复合材料。
发明内容
本发明的目的在于提供一种具有ZrW2O8连续骨架结构的Al-ZrW2O8材料复合材料的制备方法，从而在Al-ZrW2O8材料中实现铝合金相和钨酸锆相微观、宏观上都彼此约束的整体结构，获得在更宽温度范围内具有近零热膨胀系数值的Al-ZrW2O8复合材料。
