Method for connecting ceramic or ceramic-based composite material and metal material through inactive brazing filler metal
The invention belongs to the technical field of brazing welding, and particularly relates to a method for connecting a ceramic or ceramic-based composite material and a metal material through inactive brazing filler metal. According to the method, firstly, a base material to be welded is pretreated, then cerium oxide powder is added into nickel plating electroplating liquid to form a composite plating layer on the surface of TiC-Ni metal ceramic, and then the prepared TiC-Ni metal ceramic with the composite plating layer is connected with 304 stainless steel through an inactive Ag-Cu brazing filler metal brazing method. After the method is used for welding, the interface bonding strength and the mechanical property of the joint can be enhanced, the problems that the existing TiC-Ni ceramic joint is large in residual stress and low in connection strength are solved, and the method has a very good development prospect.
本发明属于钎焊焊接技术领域，具体涉及一种非活性钎料连接陶瓷或陶瓷基复合材料与金属材料的方法。该方法先对待焊接基材进行预处理，然后将氧化铈粉末添加到镀镍电镀液中在TiC‑Ni金属陶瓷表面形成复合镀层，再将制备了带有复合镀层的TiC‑Ni金属陶瓷用非活性的Ag‑Cu钎料钎焊的方法实现与304不锈钢的连接。该方法焊接之后可以增强界面结合强度和接头的力学性能，改善了目前TiC‑Ni陶瓷接头残余应力大且连接强度低的难题，具有非常好的发展前景。
