Description

铟铁复合凸点微晶磁轭
技术领域
本发明涉及铟铁复合凸点微晶磁轭。
背景技术
磁轭一种用来约束流速小于0.1m/s的流动的液体或气体的零件，可改变流经的液体或气体的路径和状态和速度等，是流速小于0.1m/s的磁液流变或气体流变等领域的重要零部件之一。
文献检索和专利检索结果，目前国内还没有含铟超过60%( Wt%)且含铟和铁共超过70%( Wt%)的铟铁复合凸点微晶磁轭的相关文献报导。
发明内容
本发明的任务是提供一种铟铁复合凸点微晶磁轭，本发明的任务是通过如下技术方案来实现的:在磁轭零件表面设一含铟超过60%( Wt%)且含铁超过8%( Wt%)且含铟和铁共超过70%( Wt%)的复合材料层，在复合材料层表面设有许多个凸点微晶，每个凸点微晶高度大于100nm且小于500μm、直径大于100nm且小于500μm的顶部为球状或近似球状、含铟超过60%( Wt%)且含铁超过8%( Wt%)且含铟和铁共超过70%( Wt%)，凸点微晶与复合材料层成为一体；零件表面复合材料层和基体材料成为一体；去除各小孔附着的材料层，形成铟铁复合凸点微晶磁轭。
所述的凸点微晶的形状和尺寸可以变化。
本发明者经过多年来的深入研究发现，用磁轭约束流动速度小于0.1m/s的液体或气体，尤其在磁流变领域的纳米磁流变液，磁轭会局部发热，且会发生微动疲劳及微动磨损。在磁轭与其它零件配合的表面形成铟铁复合凸点微晶，能有效降低磁轭热应力和降低微动疲劳性能，提升产品可靠性，因此，研究铟铁复合凸点微晶磁轭具有重要的应用价值和实用意义。
与现有技术比较，本发明的铟铁复合凸点微晶磁轭的的相关技术有重大改进：①“CN102918182A（公开日为20130206）专利”，“铟铁复合球微晶复合层(ZL201410481181.4)”、“ 铟铁复合球微晶复合层表面织构(ZL201410481180.2)”，“铟铁网状球复合微晶复合层(ZL201410481176.3)”、“ 铟铁网状球复合微晶复合层表面织构(ZL201410481178.2)”，组成成份明显不同，相应的晶体性能排列技术也明显不同。②授权专利“芯片封装结构及其装配方法（CN112820703A）”，“芯片封装结构和芯片封装结构的制备方法（CN202110407132.6）”，“焦平面阵列探测器及其制备方法（CN201711240437.2）”，“红外探测器读出电路铟凸点重置方法（CN201911142900.9）”，与本发明的铟铁复合凸点微晶磁轭的成份明显不同，微晶的成份明显不同，微晶的组成及结构和性能明显不同。③授权专利“一种铟凸点器件结构及其制备方法（CN201610316689.8）”，“一种基于铟凸点的无助焊剂回流工艺方法（CN201010515444.0）”，“红外探测器读出电路铟凸点制备方法（CN201910929868.2）”，上述3项技术的微晶体，不含铁，与本发明的成份明显不同，微晶的成份明显不同，微晶的组成及结构和性能明显不同。④ 论文“刘豫东,张钢,崔建国，等. 织构对铟凸点剪切强度的影响［J］. 红外与毫米波学报，2004,23(3)：225-228”，“LIUYu-Dong, ZHANG Gang,ZHUJi-Man, et al.Microstructure study of magnetron-sputteredindium using EBSP method[J]. Rare Metal(刘豫东,张钢,朱继满,等.EBSP对磁控溅射甸的组织研究.稀有金属), 2002, 18(4): 226— 229.”，“刘豫东，崔建国，马莒生. 衬底对铟凸点织构的影响研究[J].稀有金属材料与工程，2003,32(8)：596-599.”，报导的铟凸点织构，不含铁，与本发明的铟铁复合凸点微晶磁轭的成份明显不同，微晶的成份明显不同，微晶的组成及结构和性能明显不同。因此，本发明的相关技术具有明显重大改进。
本发明的有益效果是，具有散热性能极好、能有效降低磁轭的热应力、且提升磁轭的连接可靠性，能有效降低磁轭的微动疲劳和微动磨损，使用方便，结构简单，适用性强，且应用成本适宜，适合批量生产的特点。
