Abstract

SiO₂ glass ceramic was brazed to Ti-6Al-4V (TC4) alloy with commercially available AgCuTi and TiZrNiCu filler foil as braze alloy. SEM and XRD were carried out to study the joint interface and mechanical properties. The experimental result shows that both filler alloy could join SiO₂ glass ceramic to TC4 alloy successfully. The typical interface structure of SiO₂/TiZrNiCu/TC4 joint is SiO₂/Ti₂O + Zr₃Si₂ + Ti₅Si₃/(Ti, Zr) + Ti₂O + TiZrNiCu/TiCu/Ti (s.s)/TiZrNiCu + Ti (s.s) + Ti₂ (Cu, Ni)/TC4. The typical interface structure of SiO₂/AgCuTi/TC4 joint is SiO₂/TiSi₂ + Ti₄O₇/TiCu + Cu₂Ti₄O/Ag (s.s) + Cu (s.s)/TiCu/Ti₂Cu/Ti + Ti₂Cu/Ti-6Al-4V from SiO₂ glass ceramic to Ti-6Al-4V alloy side. The SiO₂/TiZrNiCu/TC4 joints brazed at 880°C for 5 min has the maximum shear strength 23 MPa, and the SiO₂/AgCuTi/TC4 joint brazed at 900°C for 5 min obtains the maximum shear strength 27 MPa.
