采用流延成型技术制备了不同体积分数（10%~40%） SiC_p增强Ag-Cu-Ti （SiC_p/Ag-Cu-Ti）复合钎料薄膜，按照Ag-Cu-Ti合金箔片/（SiC_p/Ag-Cu-Ti复合钎料薄膜）/Ag-Cu-Ti合金箔片的三明治结构对SiC陶瓷进行钎焊，研究了钎焊接头的微观形貌和微区成分，测试了其室温和高温抗弯强度。结果表明：SiC_p均匀分散在钎缝金属中，其周围包裹着厚0.6~0.8 μm的反应产物层；SiC陶瓷与钎缝金属结合紧密，二者之间形成了厚0.75~0.90 μm的界面反应层，界面反应层主要由TiC和Ti₅Si₃组成；随着复合钎料薄膜中SiC_p含量的增加，接头的室温抗弯强度先略微下降再增大，当SiC_p体积分数为40%时达到最高，为301 MPa，同时其600℃高温抗弯强度达到193 MPa，明显高于无SiC_p增强的普通钎焊接头的。

SiC_p reinforced Ag-Cu-Ti (SiC_p/Ag-Cu-Ti) composite brazing alloy tapes with 10vol%-40vol% SiC_p were fabricated by tape casting technique, and then the SiC ceramics were brazed with the sandwich structure of Ag-Cu-Ti alloy foil/(SiC_p/Ag-Cu-Ti composite brazing alloy tape)/Ag-Cu-Ti alloy foil. The microstructure and micro area composition of the brazed joint were studied, and the flexural strength at room temperature and elevated temperature were measured. The results show that the SiC_p, which was coated by a layer of reaction product with thicknesses of 0.6-0.8 μm, distributed uniformly in the braze metal. The SiC ceramics were tightly bonded to the braze metal. An interface reaction layer composed of TiC and Ti₅Si₃ with thicknesses of 0.75-0.90 μm was formed between the SiC ceramics and the braze metal. With the increase of SiC_p content in the composite brazing alloy tape, the flexural strength at room temperature of the joint decreased slightly and then increased, and reached the maximum value of 301 MPa when the SiC_p content was 40vol%. In addition, the high-temperature flexural strength at 600℃ reached 193 MPa, which was obviously higher than that of ordinary brazed joints without SiC_p reinforcement.
