Problems solved by technology

However, with the development of the construction industry, the above-mentioned decorative materials have revealed many insurmountable problems: aluminum-plastic panels have poor aging resistance and are flammable; surface decoration
However, due to the limitations of its own technology, explosive welding has the disadvantage of generating noise and seismic waves in the production process, which will affect the environment and residents near the explosion site, so explosive processing plants are generally built in remote mountainous areas
At the same time, the open-air operation of explosive processing is greatly affected by the weather

Embodiment 1

[0016] Embodiment 1, the production steps are as follows: a, material selection: select annealed titanium thin plate and aluminum plate, and the thickness is determined according to needs; b, adopt diffusion welding technology to compound titanium thin plate and aluminum plate to form a titanium-aluminum composite plate, specifically: The joint surface of the titanium sheet and the aluminum plate is mechanically polished and cleaned, and then placed in a vacuum container, at a vacuum degree of 10 -2 - 10 -5 Pa, keep the temperature at 520~600°C, and the pressure at 6~12N / mm 2 Under the process conditions, vacuum diffusion welding is carried out, and the vacuum diffusion welding time is 0.5~1 hour; then naturally cool to room temperature, open the vacuum container, and take out the titanium-aluminum composite board; c. Level the titanium-aluminum composite board, and then use mechanical Method Fix the four sides of two titanium-aluminum composite panels as a group, with the m...

Embodiment 2

[0018] Embodiment two, its production steps are as follows: a, material selection: select the titanium thin plate and aluminum plate through annealing, thickness is determined according to need; 1. The aluminum plate is prefabricated according to the structure combination of titanium and aluminum, and the titanium-aluminum composite plate is cold-rolled by a rolling mill; c. Then it is sent to a heat treatment furnace (general vacuum heat treatment furnace), and the vacuum degree is 10 -2 Pa~10 -5 Diffusion welding is carried out under the vacuum protection of Pa or under the protection of inert gas argon, the heating temperature is 550 ℃ ~ 600 ℃, heat preservation for 1 hour, and then take out the composite board after cooling to room temperature with the furnace; d. Put the combined composite board on heating In the furnace, under the condition that the temperature of the clad plate is 350°C~450°C, warm rolling is carried out, and the pass reduction rate is kept between 8%~1...

Abstract

The invention relates to a production method of titanium-aluminium composite plates. The production method comprises the following technical points: compositing titanium sheets and aluminium plates together by adopting a diffusion welding technology so as to form the titanium-aluminium composite plates; carrying out leveling on the titanium-aluminium composite plates, and then fixing two titanium-aluminium composite plates as a group by adopting a mechanical method; arranging the combined titanium-aluminium composite plates in a heating furnace, carrying out warm rolling under the condition that the temperature of the composite plates is 350-450 DEG C, maintaining the reduction in pass to be between 8% and 16%, and carrying out 4-7 passes in total; disconnecting the combination of the composite plates by warm rolling, carrying out cold rolling on single composite plate, maintaining the reduction in pass to be between 6% and 12%, and carrying out 3-7 passes in total. The composite plates is treated by diffusion welding and then warm rolling, so that the limitation of difficult thickness processing and purchase of the raw titanium sheets in the diffusion welding process of the titanium-aluminium composite plates is overcome, a thinner firm metal coating layer can be obtained, and further the application of the titanium-aluminium composite plates is wider and more economical.

Description

technical field [0001] The invention relates to the technical field of metal composite materials, including composite metal material production, composite metal material cold forming, surface electrochemical treatment and other subject industries, and specifically relates to a production method of a titanium-aluminum composite plate. Background technique [0002] At present, there are many kinds of decorative materials on the market: traditional wood products, mostly interior materials; modern decorative materials include aluminum-plastic composite materials, stainless steel plates, etc., which are characterized by good decoration. However, with the development of the construction industry, the above-mentioned decorative materials have revealed many insurmountable problems: aluminum-plastic panels have poor aging resistance and are flammable; Decorative surface. [0003] Titanium metal is a modern high-tech material, widely used in aerospace, fine chemical, medical and othe...
