| 摘 要： | 采用Ti40Zr25Ni15Cu20非晶钎料进行了Si3N4陶瓷真空钎焊连接,利用SEM、EDX等微观分析手段,研究了钎焊界面的微观结构,得出界面反应层有两部分组成,接头界面微观结构为Si3N4/TiN/Ti-Si,Zr-Si化合物/钎缝中心;在相同钎焊工艺条件下,研究对比了晶态和非晶态钎料钎焊接头的强度,发现非晶态钎料钎焊的接头强度大大超过用晶态钎料钎焊的接头.

| Abstract: | Si3N4 ceramic is brazed with Ti40Zr25Ni15Cu20 amorphous filler metal,and the effect of brazing parameter on interfacial microstructure and joint strength was discussed.The interfacial microstructure is composed of two parts which are TiN and Ti-Si,Zr-Si compound respectively with the SEM,EDX etc.Under the same experiments conditions,the joint strength brazed with amorphous filler metal increased a lot compared with the crystalline. |

| Keywords: | Ti-Zr-Ni-Cu brazing filler metal amorphous filler metal Si3N4 ceramic interfacial microstructure bonding strength |
