Microstructure and strength of Si₃N₄ joint brazed with Ti40Zr25Ni15Cu20 amorphous brazing alloy

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.
