Abstract

In this study, a commercially available Ag-Cu-Ti braze alloy foil was used to join SiO₂ glass ceramic and 30Cr3 high-tensile steel. According to experimental observations, the interface structure can be expressed as SiO₂ glass ceramic/TiSi₂ + Ti₄O₇/Ti₂Cu + Cu₃Ti₃O/Ag(s.s) + Cu(s.s)/TiFe₂/30Cr3 high-tensile from SiO₂ glass ceramic side to 30Cr3 high-tensile steel side. With the increased brazing temperature, the thickness of Ti₂Cu + Cu₃Ti₃O layer increases at first and then reduces. The thickness of TiSi₂ + Ti₄O₇ layer and that of TiFe₂ layer rise with the increased brazing temperature. According to experimental results of the mechanical properties, the maximum shear strength is 37 MPa when the joint was brazed at 900 °C for 5 min.
