Carbon-based material/metal connection method based on Cu-C/Ti instantaneous liquid phase in-situ reaction

The invention discloses a carbon-based material/metal connection method based on a Cu-C/Ti instantaneous liquid phase in-situ reaction, which comprises the following steps of: treating the surface of a metal matrix by adopting an electrochemical deposition method to co-deposit Cu-C alloy on the metal surface to prepare a composite matrix, placing a Ti foil and a Cu foil with certain thickness between a carbon-based material matrix and the composite matrix to form a to-be-welded part, and welding the to-be-welded part to form the carbon-based material/metal connection method based on the Cu-C/Ti instantaneous liquid phase in-situ reaction. And welding in a vacuum hot-pressing sintering furnace to finish the connection of the carbon-based material/metal. According to the method, TiC granules can be generated in situ in the carbon-based material/metal welding seam, the joint stress is effectively relieved, and the joint strength is improved. The shear strength of the graphite/copper joint obtained by the method
