| Abstract | 采用镍基共晶钎料BNi-7对Ti（C，N）基金属陶瓷与17—4PH沉淀硬化不锈钢行了真空钎焊连接。研究了钎焊温度和焊缝厚度对焊接接头力学性能和微观结构的影响。结果表明，BNi-7对金属陶瓷粘结相具有较强的溶解能力，这是熔降元素（磷）能够在金属陶瓷侧大范围分布、钎焊接头获得良好界面结合的主要原因。随钎焊温度升高，磷在金属陶瓷侧的分布区域逐渐扩大，在1100℃保温60min、焊缝厚度为50μm的工艺下获得了最高的接头抗剪强度454MPa。 |
| Other Abstract | The Ti（C,N） cermet and 17-4PH precipitation-hardened stainless steel were brazed in vacuum using nickel-based eutectic filler BNi-7. The effects of brazing temperature and brazing seam thickness on the microstructure and shear strength of the brazed joints were investigated. BNi-7 filler had a strong dissolution ability to the binder of the Ti（C,N） cermet. This is beneficial to the wide distribution of melting point depressant （phosphorous） in the Ti（C,N） cermet side and producing a good interfacial bonding. The distribution zone of phosphorous in the Ti（C,N） cermet side that is adjacent to the brazing seam increased as the brazing temperature rose. A maximum shear strength of 454 MPa was achieved at a brazing temperature of 1100℃ and a brazing time of 60 min with a brazing seam thickness of 50μm. |
