چکیده انگلیسی
C/C composites were successfully brazed to Nb substrate using Cu75Pt25 filler metal. The typical interfacial microstructure of brazed joints was C/C composites/NbC/Nb(s, s)/Cu(s, s)/NbPt2/Nb3Pt/Nb(s, s)/Nb. The effect of brazing temperature on the interfacial microstructure and joints properties were investigated in details. With the increase of temperature, the Nb-Pt reaction layer thickened and the thickness of brazing seam declined. The thickness of Nb(s, s) layer at C/C composites side increased gradually with the increase of temperature and then declined when brazing temperature was over 1160â¯Â°C. The optimal average shear strength of 26.7â¯MPaâ¯at room temperature and highest shear strength of 17.6â¯MPaâ¯at 600â¯Â°C were obtained when the joints were brazed at 1160â¯Â°C for 20â¯min.
