首次研究了在Ａｌ２Ｏ３陶瓷与金属Ｎｂ的钎焊面之间加入一层金属Ｍｏ网，可大幅度提高接头的焊接强度，经用Ｎｉ５１Ｔｉ４９和Ｃｕ５２Ｎｉ１８Ｔｉ３０两种钎料焊接，焊后强度均提高５０％以上，断裂特征由陶瓷中的大块破损转变为沿界面的混合型断裂。金属网的加入对钎料凝固收缩应力产生了分割相消的作用，从而有效降低了焊接接头的残余应力 For the first time, it has been studied that adding a layer of metallic Mo mesh between the brazing surfaces of Al2O3 ceramic and metallic Nb can greatly improve the welding strength of the joints. After welding with both Ni51Ti49 and Cu52Ni18Ti30 brazing filler metals, the post-weld strength is increased by more than 50% , The fracture characteristics are transformed from massive breakage in ceramics to mixed fracture along the interface. The addition of metal mesh has the effect of splitting and eliminating the solidification shrinkage stress of the solder, thus effectively reducing the residual stress of the welded joint
