Keywords： Brazing

A commercially available Ti47Zr28Cu14Ni11 (at.pct) amorphous filler foil was used to join ZrO2 ceramic and Ti-6Al-4V alloy.According to experimental observations,the interface microstructure accounts for the mechanical properties of the joints.The effects of brazing conditions and parameters on the joint properties were investigated.The joint shear strength showed the highest value of about 108 MPa and did not monotonously increase with the brazing time increasing.It was shown that decreasing of brazing cooling rate and appropriate filler foil thickness gave higher joint strength.
