  • In order to achieve the complete joint of Al2O3 ceramics/5005 aluminum alloy at the low temperature, the Al2O3 ceramic were metallized with the Ag-Cu-Ti powder. It was shown that a continuous Ti3Cu3O reaction layer adjacented to the Al2O3 ceramic was confirmed. The interfacial structures and formation of the active metallized Al2O3/Al-Si/ 5005 aluminum alloys ceramic high-frequency induction brazed joints were analyzed. It was shown that the microstructure of the 5005 aluminum alloys/Al-Si/Al2O3 ceramic joint brazed at 600 ℃ for 1 min was: 5005 aluminum alloys/α-Al+Al-Ag-Cu eutectic +Si crystal /AlSi alloy +α-Al+ξ-Ag2Al/Ti3Cu3O/ Al2O3ceramic. The maximum shear strength was 52 MPa.
