Porous ceramics are favored due to their high strength, high hardness, good corrosion resistance and low density. Porous ceramics have poor extensibility, poor machinability, and difficult machining, making the fabrication of ceramic composites and large-scale components very difficult. However, many components in manufacturing today involve connections between porous ceramics and between porous ceramics/metals.

本发明机理:在经历超声波振动的液态水或熔融金属内部放置毛细管时,水或金属会沿导管内壁以很快的速度上升,该现象就是“声致毛细”作用。在此过程中,液体在毛细管内的上升不依赖液体对管内壁的润湿情况,在不润湿的情况下液体仍然可以渗入的毛细管内部。一般来讲,传统钎料对陶瓷的润湿性较差,即使将陶瓷热浸到钎料中很长一段时间,钎料也不会润湿并渗入陶瓷。利用声致毛细现象可以很好的解决液态钎料难以渗入多孔陶瓷的难题。除此之外,液态钎料在经历超声波振动时会产生空化,空化泡的溃灭会产生局部达到几千度的高温,也会产生速度很高的微射流,利用这两个现象可以解决陶瓷表面难润湿的问题,实现钎料对陶瓷的润湿。多孔陶瓷的空隙一般较小,而较窄间隙内可产生更强作用的声空化现象,利于液态钎料和陶瓷的连接。The mechanism of the invention: when a capillary tube is placed inside the liquid water or molten metal that has undergone ultrasonic vibration, the water or metal will rise along the inner wall of the tube at a fast speed, and this phenomenon is the "acoustic capillary" effect. In this process, the rise of the liquid in the capillary tube does not depend on the wetting of the inner wall of the tube by the liquid, and the liquid can still penetrate into the inside of the capillary tube without wetting. In general, conventional solders have poor wettability to ceramics, and even if the ceramics are hot-dipped into the solder for a long time, the solder will not wet and penetrate the ceramic. The sonocapillary phenomenon can be used to solve the problem that liquid solder is difficult to penetrate into porous ceramics. In addition, the liquid solder will generate cavitation when it undergoes ultrasonic vibration, and the collapse of the cavitation bubble will generate a high temperature of several thousand degrees locally, and will also generate a high-speed micro-jet. These two phenomena can be used to Solve the problem that the ceramic surface is difficult to wet, and realize the wetting of the ceramic by the brazing filler metal. The voids of porous ceramics are generally small, and a stronger acoustic cavitation phenomenon can be generated in the narrower gaps, which is beneficial to the connection between the liquid solder and the ceramics.
本发明的有益效果是:The beneficial effects of the present invention are:
1、陶瓷的选择灵活。本发明可以焊接任意多孔陶瓷,不受陶瓷成分的限制。1. The choice of ceramics is flexible. The present invention can weld any porous ceramic, and is not limited by the ceramic composition.
2、钎料的选择和成分配比灵活。本发明可使用任意钎料,高低温均可,且钎料成分配比灵活,可以是单一成分,也可以是复合钎料。2. The selection of solder and the proportion of components are flexible. The present invention can use any brazing filler metal, both high and low temperature, and the brazing filler metal has a flexible composition distribution ratio, which can be a single component or a composite brazing filler metal.
3、焊接过程温度范围广。本发明可根据试件的使用情况选择合适的钎料,而后根据钎料成分选择焊接温度。如Sn-9Zn钎料的焊接温度可以为200℃或以上,Zn-5Al钎料的焊接温度可以为400℃或以上,Al-12Si的焊接温度可以为600℃或以上。3. The welding process has a wide temperature range. According to the present invention, suitable brazing filler metal can be selected according to the use condition of the test piece, and then the welding temperature can be selected according to the brazing filler metal composition. For example, the soldering temperature of Sn-9Zn solder can be 200°C or above, the soldering temperature of Zn-5Al solder can be 400°C or above, and the soldering temperature of Al-12Si can be 600°C or above.
4、超声的施加位置灵活。焊接过程中,超声波可以加载在陶瓷上,也可以施加在夹具上;超声可以持续施加,也可以间隙施加。4. The application position of ultrasound is flexible. During the welding process, ultrasonic waves can be loaded on the ceramics or applied to the fixture; ultrasonic waves can be applied continuously or intermittently.
5、接头的强度高。液态钎料通过超声波毛细及空化作用,渗入到母材一定的深度,形成了致密的复合材料层,该层焊接之后强度比多孔的母材强度高,即接头受力时从母材断裂,且液态钎料渗入到母材后,使得母材强度提高,提高32%以上。5. The strength of the joint is high. The liquid brazing filler metal penetrates into the base metal to a certain depth through ultrasonic capillary action and cavitation, forming a dense composite material layer. And after the liquid brazing filler metal penetrates into the base metal, the strength of the base metal is increased by more than 32%.
6、成本低,适应性强,焊接效率高。在大气环境下即可完成焊接,几乎不受周围施工环境的影响,且焊后不需保温。6. Low cost, strong adaptability and high welding efficiency. The welding can be completed in the atmospheric environment, almost unaffected by the surrounding construction environment, and no heat preservation is required after welding.
7、本发明的使用范围广,使用于各种厚度,各种复杂件,适用于同种或异种多孔陶瓷的焊接。7. The present invention has a wide range of applications, is used in various thicknesses and various complex parts, and is suitable for welding of the same or different types of porous ceramics.
