摘　　要：采用Cu作为中间层对银与07Cr16Ni6高强不锈钢进行接触反应钎焊,测试分析钎焊接头的性能和组织。结果表明,随着中间层厚度的增加,Cu向银基体的扩散深度增加,钎焊接头强度先增大后减小。中间层厚度为20~30μm时,银与高强不锈钢实现了可靠连接,钎角饱满,钎缝内部致密,接头抗剪强度达到131 MPa。Contact reaction brazing of silver and 07Cr16Ni6 high-strength stainless steel with Cu as the interlayer was carried out in this paper,and the properties and microstructure of brazing joints were tested and analyzed.The results show that,with the increase of interlayer thickness,the diffusion depth of Cu to the silver matrix increases,and the strength of brazed joint first increases and then decreases.When the thickness of the intermediate layer is 20~30μm,the silver is reliably connected to the high-strength stainless steel,with full brazing angles,tight joints,and the shear strength is up to 131 MPa.
