Active amorphous brazing filler metal for brazing ZrB2-SiC ceramic materials, preparation method for active amorphous brazing filler metal and brazing process
The invention discloses active amorphous brazing filler metal for brazing ZrB2-SiC ceramic materials, a preparation method for the active amorphous brazing filler metal and a brazing process, particularly relates to Cu-Ti-Ni-Zr high-temperature active amorphous brazing filler metal for brazing ZrB2-SiC ultra-high-temperature ceramic materials, a preparation method for the Cu-Ti-Ni-Zr high-temperature active amorphous brazing filler metal and a brazing process, and belongs to brazing filler metal in the amorphous and metallurgy fields. The components of the brazing filler metal comprise, by atomic percentage, 36.0-42.0% of Cu, 30.0-35.0% of Ti, 16.0-23.0% of Zr and the balance Ni. The melting temperature of the active amorphous brazing filler metal is 1110-1150 K, and the brazing temperature is 1183-1273 K. The Cu-Ti-Ni-Zr high-temperature active amorphous brazing filler metal obtained through the rapid condensation technology has good wettability. The room temperature shearing strength of the ZrB2-SiC ultra-high-temperature ceramic materials brazed through the amorphous brazing filler metal in a vacuum brazing mode can be as high as 160 MPa and much higher than that of Cu-based and Ag-based brazing filler metal.
