陶瓷与金属直接钎接的关键问题是钎料的选择．采用活性钎料进行陶瓷与金属的直接钎接，并对接头进行了机械拉伸试验和金相分析，结果表明，钎料的选择是成功的。还介绍了钎料的冶炼工艺． The key issue of ceramic and metal direct brazing is the choice of brazing material. The active brazing filler metal was used for the direct brazing of ceramic and metal. The mechanical tensile test and metallographic analysis of the joint were carried out. The results show that the selection of brazing filler metal is successful. Also introduced the solder smelting process.
