    摘要:

    在 1.8 ks,10 73 K～ 1173 K條件下對(duì) Al2 O3/ ( Ag72 Cu2 8) 97Ti3/ Ti- 6Al- 4 V進(jìn)行了釬焊試驗(yàn)。通過掃描電鏡、波譜、能譜、X射線衍射對(duì)界面結(jié)構(gòu)進(jìn)行了分析。小于 112 3 K的界面結(jié)構(gòu)為 Al2 O3/ Cu2 Ti4 O/ Cu4 Ti3/ Ag- Cu共晶 +富 Ag相 + Ti固溶體 ;1173 K的界面結(jié)構(gòu)為 Al2 O3/ Cu3Ti O5+ Cu Al2 O4 / Cu4 Ti3/富 Ag相。采用拉剪試驗(yàn)測(cè)試了接頭剪切強(qiáng)度。在 1.8ks,112 3 K時(shí)剪切強(qiáng)度最高達(dá)到 189MPa,大于或小于 112 3 K接頭強(qiáng)度呈下降趨勢(shì)。

    Abstract:

    The Al_2O_3 ceramics was bonded with Ti-6Al-4V using (Ag_ 72Cu_ 28)_ 97Ti_3 as filler metal under the conditions of 1 073 k~1 173 K and 18 ks. The interface structure and formation mechanism of joints were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS). It was found that the interface structure of diffusion-bonded joints is Al_2O_3/Cu_2Ti_4O/Cu_4Ti_3/Ag-Cu eutectic+rich Ag phase+Ti soild solution for bonding temperature below 1 123 K. For bonding temperature of 1 173 K, the interface structure is Al_2O_3/Cu_3TiO_5+CuAl_2O_4/Cu_4Ti_3/rich Ag phase. Strength of the Al_2O_3/(Ag_ 72Cu_ 28)_ 97Ti_3/Nb joint reaches 189 MPa for bonding temperature of 1 123 K and 18 ks. The lower bonding temperature, or the higher bonding temperature, the lower strength of joints.
