一种高强度可溶解铝合金及其制备方法 技术领域
本发明涉及功能材料技术领域，特别涉及一种高强度可溶解铝合金及其制备方法。
背景技术
在油田开采过程中，通常需要大量井下工具，最为理想的状况就是这些工具既能在服役期间满足使用要求，又能在失效后迅速降解，保持井筒畅通，避免了回收构件时浪费资源的问题。此外，有些工具须在井下存在的高温、高压工况下服役，这就要求其不但可溶，还必须具有高的机械强度，以满足一定的承压要求。因此，研制一种高强度可溶解材料以制备油田井下开采工具成为目前急需解决的技术难题。
目前常见的可溶解材料主要为有机高分子材料，但其无法承受高温、高压等压裂要求，而且须在光照等特殊条件下使用，对压裂环境要求苛刻。此外，近年来研发的用于生物领域的可溶解无机材料，如镁合金、生物陶瓷等材料溶解速度缓慢，而且要有一定的生物环境，也无法满足压裂需求。
美国专利US 2007/0181224 A1(公开日为2007年8月9日)中公开了一种组合物，该组合物包括占主要比例的一种或多种活性金属，以及占少量比例的一种或多种合金化产物。主要包含元素周期表第I和II族中的金属及合金化产物，例如，功能合金镓(Ga)、铟(In)、锌(Zn)、铋(Bi)和铝(Al)。该组合物的特征在于其在特定的条件下可控制其活性和可降解，但是由于材料具有很强的金属特性，抗压强度仅能达到几十MPa。类似地，中国专利200910130736.X(公开日为2009年10月21日)中也采用以上几种金属及合 金化合物的熔体或粉末，得到可溶性合金，但并未涉及机械性能。
油田井下工具如可溶桥塞卡瓦支撑部分对机械强度要求较高(500-600MPa)，因此，非常希望设计开发出一种兼具高机械性能与可溶性能的材料。
