摘　　要：在１．８　ｋｓ、１　０７３～１　１７３　Ｋ条件下对Ａｌ２Ｏ３／（Ａｇ７２Ｃｕ２８）９７Ｔｉ３／Ｔｉ－６Ａｌ－４Ｖ进行了钎焊试验。通过扫描电镜、波谱、能谱和Ｘ射线衍射对界面反应产物进行了测试，确定了界面结构，并讨论了这些反应产物形成的可能性。结果表明，温度小于１　１２３　Ｋ的界面结构为Ａｌ２Ｏ３／Ｃｕ２Ｔｉ４Ｏ／Ｃｕ４Ｔｉ３＋Ｃｕ固溶体／Ａｇ－Ｃｕ共晶　＋　富Ａｇ相；温度１　１７３　Ｋ的界面结构为Ａｌ２Ｏ３／Ｃｕ３ＴｉＯ５　＋　ＣｕＡｌ２Ｏ４／Ｃｕ４Ｔｉ３／富Ａｇ相＋　Ｃｕ４Ｔｉ３。Ceramic Al2O3 is bonded with Ti-6Al-4V using (Ag72Cu28)97Ti3 as filler metal at the bonding temperature of 1 073-1 173 K for 1.8 ks．The interface reaction products of joint are investigated by scanning electron microscopy(SEM)，X-ray diffraction(XRD) and energy dispersive spectroscopy (EDS)．So the interface structure is given．The formative conditions of these reaction products are also studied．It has been found that the interface structure of diffusion-bonded joints bonded under 1 123 K is Al2O3/Cu2Ti4O/ Cu4Ti3 + Cu solid solution /Ag-Cu eutectic + rich Ag phase．At the temperature of 1 173 K the interface structure is Al2O3/Cu3TiO5+ CuAl2O4/ Cu4Ti3/rich Ag phase + Cu4Ti3．
