摘要：

The polycrystalline ZrO2-3mol.%Y2O3 was brazed to Ti-6Al-4V using a Ti47Zr28Cu14Ni11 (at.%) amorphous ribbon at 1123 K in a high vacuum. The microstructure of the interface and evolution mechanism of the joint was investigated. The experimental result showed that the typical interfacial microstructures of the joints consisted of ZrO2/TiO+TiO2+Cu2Ti4O+Ni2Ti4O/alpha-Ti+(Ti, Zr)(2)(Cu, Ni) eutectic/(Ti, Zr)(2)(Cu, Ni)/acicular Widmanstaten structure/Ti-6Al-4V alloy. The microstructure of the brazed joint was related to the solution and chemical reaction among atoms during brazing. According to the mechanical property tests the joint brazed at 1123 K for 30 min obtained the maximum shear strength 63 MPa. Both the white block intermetallic compound (Ti, Zr)(2)(Cu, Ni) and the coarse alpha-Ti+(Ti, Zr)(2)(Cu, Ni) eutectic structure should be avoided forming in the brazed joint.
