▎ 摘　　要

NOVELTY - Soldering titanium-aluminum alloy and ceramic with a graphene barrier layer comprises preparing a graphene layer on the surface to be welded of the titanium-aluminum alloy by liquid phase transfer, placing a copper-containing solder foil between the surface to be welded of the titanium-aluminum alloy and welding the ceramic surface and soldering. USE - The method is useful for soldering titanium-aluminum alloys and ceramics with a graphene barrier layer. ADVANTAGE - The method ensures thickness of the reaction layer and has good mechanical properties.
