A titanium aluminium composite plate

Abstract

The invention discloses a titanium aluminium composite plate, and belongs to the field of plates. The surface of a titanium plate is covered with a titanium oxide film, and under the condition that only one surface of an aluminum plate is covered with the titanium plate, the other surface of the aluminum plate is covered with an aluminum oxide film, so that corrosion resistance of the titanium aluminium composite plate is enhanced. By setting a thickness range of each plate, the problem that heavy weight and poor sound-insulation and heat-insulation effects of titanium aluminium composite plates in the prior art hinder popularization and application of the titanium aluminium composite plates is overcome under the condition of adopting less titanium materials as a panel. Under the condition of ensuring feasible practical application, the weight of the titanium aluminium composite plate is further reduced, sound-insulation and heat-insulation properties of the titanium aluminium composite plate are enhanced, the material using cost of the titanium aluminium composite plate is reduced, and the titanium aluminium composite plate is high in thermal conductivity and long in service lifetime.

Description

technical field [0001] The invention relates to a plate, in particular to a titanium-aluminum composite plate. Background technique [0002] As a structural material, titanium has many excellent properties, such as low density, high strength, corrosion resistance, high temperature impact resistance, etc., but the price of titanium material is relatively high; although aluminum has low price, low density and good thermal conductivity, it is corrosion resistant and high temperature resistant. Impact performance is poor. [0003] Layered titanium-aluminum composite panels not only have a lower density than titanium, but also have the advantages of aluminum's excellent thermal conductivity and titanium's corrosion resistance and high temperature resistance. Therefore, the layered titanium-aluminum composite plate is expected to be popularized and applied in the fields of aviation, cooking utensils, chemistry, naval ships, and special solder. [0004] However, the titanium-alum...
