以铜磷合金粉末为中间层,采用瞬间液相扩散连接方法在910~960℃保温30 min条件下对304不锈钢复合滤网进行了连接,对界面微观组织和元素扩散进行了分析。结果表明,在930℃保温30 min时,粗丝与细丝之间形成无焊缝连接,而冲孔板与粗丝之间形成焊缝;连接温度对降熔元素P的扩散影响很大,随连接温度升高,不锈钢复合网的冲孔板与粗丝之间所形成的焊缝宽度不断减小,在960℃保温30 min时,冲孔板与粗丝之间、粗丝与细丝之间均形成无焊缝连接,孔形结构没有明显变化。
Copper-phosphorus alloy powder as the intermediate layer, using instant liquid-phase diffusion bonding method at 910 ~ 960 ℃ for 30 min under the conditions of 304 stainless steel composite mesh connected to the interface microstructure and elemental diffusion were analyzed. The results show that when the wire is heated at 930 ℃ for 30 min, there is no weld connection between the thick wire and the thin wire, and the weld is formed between the punching plate and the thick wire. The connection temperature has a great influence on the diffusion of the melting element P, With the increase of the connection temperature, the width of the weld formed between the punched plate and the thick wire of the stainless steel composite mesh continuously decreases. When the temperature is kept at 960 ℃ for 30 min, the thick and thin wires Between the formation of no weld connection, no significant change in the hole structure.
