Active brazing of SiO2 glass ceramic to TC4 alloy

    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℃ for 5 min has the maximum shear strength 23 MPa, and the SiO2/AgCuTi/TC4 joint brazed at 900℃ for 5 min obtains the maximum shear strength 27 MPa.
