Problems solved by technology

However, the solid-liquid composite method has certain disadvantages, that is, because the melting point of aluminum is much lower than that of titanium, it can only be coated with aluminum on the surface of titanium or titanium alloy, and the thickness of the coating is only 0.5-2mm
On the other hand, the bonding strength between the two metal layers of the layered titanium-aluminum composite plate prepared by rolling composite or thermal diffusion composite method alone is insufficient, which limits its performance and application fields.

Abstract

The invention discloses a method for manufacturing a laminated titanium-aluminum composite board, and belongs to the technical field of laminated composite material manufacturing and machining. According to the method, firstly, the surface of a combined titanium or titanium alloy board is coated with a layer of aluminum or aluminum alloy through solid-liquid fusion covering, then compositing between an aluminum or aluminum ally board and the coated board is achieved through thermal diffusion or hot-rolling-bonding to obtain a laminated titanium-aluminum composite board blank, and finally a finished product of the laminated titanium-aluminum composite board is obtained through cold rolling deformation. Compared with an explosion and roll cladding method, cost and process difficulty of the method are greatly reduced, and production efficiency is greatly improved; compared with a traditional solid-liquid compositing method, the titanium-aluminum composite board manufactured through the method is good in performance, the thickness of the aluminum layer is large, and materials are saved; the manufactured titanium-aluminum composite board has the advantages of good heat conductivity of aluminum, high temperature resistance of titanium and the like, and can be widely used in the fields of aerospace, petrochemical engineering, ship manufacturing, power electronics and the like.
