Abstract

In this paper, SiO₂ glass ceramic was brazed to Ti-6Al-4V alloy with a commercially available AgCuTi filler foil as braze alloy. Various brazing heating cycles were carried out to study the effects of brazing parameters on the joint interface and mechanical properties. The experimental result shows that the typical interface structure of the joints 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 microstructure of the brazed joint is related to the solution and chemical reaction among atoms during the brazing. According to the mechanical property tests, the joint brazed at 900 °C for 5 min obtains the maximum shear strength 27 MPa.
