The following paper investigated the vacuum brazing joining of Ti3AlC2 ceramic and 40Cr steel with Ag-Cu-Ti filler metal at 850Â Â°C. A characterization of the brazing joint revealed that it consisted of the Ti3AlC2 ceramic, the brazing seam, and the 40Cr steel. There were four phase types found in the brazing seam that included AlCu2Ti, Al4Cu9, Cu[s, s], and Ag[s, s]. These occurred as a result of the interface reactions, which precipitated from the liquid alloy during solidification. When the brazing time was increased from 10Â min to 30-60Â min, there was a formation of a continuous reaction layer and a strong combination at the filler metal/40Cr steel interface. This led to the transformation of the joint facture position from the filler metal/40Cr steel interface to the Ti3AlC2/filler metal interface, thus resulting a significant enhancement of the joint shear strength from 27.7Â MPa (10Â min) to 196.4Â MPa (30Â min), and again to 191.3Â MPa (60Â min). The results showed that the optimal brazing time was 30Â min.
