Method for connecting aluminum oxide ceramic and aluminum through composite glass solder
The invention discloses a method for connecting aluminum oxide ceramic and aluminum through composite glass solder, and belongs to the technical field of dissimilar material welding. Micron-sized Al particles are added into the glass solder as a reinforcing phase, to-be-welded surfaces of the aluminum oxide ceramic and 1060Al are treated in advance, and the to-be-welded surfaces of the aluminum oxide ceramic and the 1060Al are treated in advance; a to-be-welded connecting piece of the polished ceramic, the glass soldering paste and the polished Al is obtained from top to bottom, and low-temperature high-quality connection of the aluminum oxide ceramic and the 1060Al is achieved after the to-be-compounded glass solder is heated and softened; the problem that the glass solder is brittle is solved, and the strength of a welding seam is improved; the Al particles are added, so that the fine grain strengthening effect is achieved; in addition, the problem that in the existing ceramic and metal connecting process, due to the difference of thermal expansion coefficients, a welded joint is unfavorable is solved, and the method is low in cost, easy to operate and environmentally friendly.
本申请公开了一种复合玻璃焊料连接氧化铝陶瓷和铝的方法，其属于异种材料焊接技术领域，将微米级Al颗粒作为增强相加入至玻璃焊料中，并预先对氧化铝陶瓷和1060Al的待焊接面进行处理，按照自上而下的顺序得到打磨陶瓷、玻璃焊膏、打磨Al的待焊连接件，加热待复合玻璃焊料软化后，实现氧化铝陶瓷和1060Al的低温高质量连接；解决了玻璃焊料较脆的问题，提高了焊缝的强度；Al颗粒的添加达到了细晶强化的效果；此外还解决了现有陶瓷和金属连接过程中由于热膨胀系数差异对焊接接头不利的问题，且该方法成本低，操作简单，绿色环保。
