Abstract:
In order to achieve the complete joint of Al
2O
3 ceramics/5005 aluminum alloy at the low temperature, the Al
2O
3 ceramic were metallized with the Ag-Cu-Ti powder. It was shown that a continuous Ti
3Cu
3O reaction layer adjacented to the Al
2O
3 ceramic was confirmed. The interfacial structures and formation of the active metallized Al
2O
3/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/Al
2O
3 ceramic joint brazed at 600 ℃ for 1 min was: 5005 aluminum alloys/
α-Al+Al-Ag-Cu eutectic +Si crystal /AlSi alloy +
α-Al+
