NOVELTY - Method for brazing zirconium carbide-silicon carbide ceramics and titanium alloy (TC4) involves (a) adding zirconium hydride powder as a dispersant to pure copper powder, mixing thoroughly and spreading uniformly on the silicon wafer, (b) using the plasma enhanced chemical vapor deposition method to grow graphene on the surface of the copper powder on the silicon wafer to obtain copper product (VFG-copper), (c) mixing 80-92 %mass VFG-copper and zirconium hydride (remaining quantity) and mixing uniformly to obtain a mixed powder, (d) carrying out tableting processing on the obtained mixed powder to obtain a solder foil, (e) pre-cleaning the zirconium carbide-silicon carbide ceramics and titanium alloy (TC4) to be brazed, and (f) placing the obtained solder foil between the pre-cleaned zirconium carbide-silicon carbide ceramic and titanium alloy, assembling, brazing and cooling with furnace to obtain the product. USE - The method is useful for brazing zirconium carbide-silicon carbide ceramics and titanium alloy (TC4). ADVANTAGE - The method solves problems of poor wettability of brazing filler metal to base material, easy generation of brittle compounds in the brazing seam, excessive dissolution of the metal base material and large residual stress in the joint during brazing.
