Description
Technical field
The present invention relates to the metallic composite technical field, comprise the composite material making, composite material is cold-formed, a plurality of subject industries such as surface electrochemistry processing, specifically a kind of production method of titanium aluminum composite plate.
Background technology
At present, ornament materials is various in style on the market: traditional is woodwork, is mostly interior material; The Modern Decorative material has aluminium plastic composite material, corrosion resistant plate etc., is characterized in good decorative property.But along with the development of building industry, above-mentioned ornament materials is showed many problems that are difficult to overcome: the aluminium-plastic panel ageing resistace is poor, and is inflammable; Corrosion resistant plate weight is heavier, the weather-resistant poor performance, and dirt is easily adhered on the surface, finally influences decorative surface.
Titanium is the modern high technology material, is widely used in Aero-Space, fine chemistry industry, and industries such as medical treatment are new kinds of ornament materials.Its weight is low weight, does not burn, and through anodized surface of metal titanium colourful color can be arranged, and its weather-resistance is very strong, is desirable ornament materials.But it costs an arm and a leg, and gives and promotes the use of the difficulty of bringing financial aspect.Titanium Al bimetal composite can well address the above problem: the titanium thin plate both can keep primary characteristic, can alleviate the weight of titanium again; Aluminum metal is in light weight, and can there be good antiseptic property on the surface through anodization; Titanium Al bimetal composite plate is in conjunction with firm, and overall weight and intensity are moderate, and fire resistance can satisfy the technological requirement of ornament materials, is the superfine product of senior building inside/outside decorative material, also is the first-selection of high-grade Electric Apparatus Chassis material.
But in the prior art, the manufacture craft of titanium Al bimetal composite plate is imperfection also, as explosive welding is a kind of technology of making different layered metal composite plate, has been widely used in the production of bilayers such as titanium/steel, charcoal steel/stainless steel, copper/aluminium, copper/steel or multilayer composite board material.But because the limitation of self technology, explosive welding has and produces noise and seismic wave in process of production, and the shortcoming that near the environment explosive field and resident are impacted is so the blast processing space is generally all built remote mountain area in.It is bigger that the open work of blast processing is simultaneously influenced by weather.So a kind of production method of new titanium aluminum composite plate is that research institute of the present invention exists.
Summary of the invention
The objective of the invention is for the production method of feasible, the safe and reliable titanium aluminum composite plate of a kind of convenience is provided.
Technical scheme of the present invention is: the production method of this titanium aluminum composite plate, and its technical essential is: production stage is as follows: a, selection: select annealed titanium sheet metal and aluminium sheet; B, employing Pervasion Weld Technology are combined with each other titanium sheet metal and aluminium sheet, form titanium aluminum composite plate; C, titanium aluminum composite plate is smoothed, adopt mechanical means that two titanium aluminum composite plates are fixed as one group then, the Titanium face is interior, and the aluminum metal face outside; D, will place heating furnace through the titanium aluminum composite plate of combination, be under 350 ℃ ~ 450 ℃ the condition, to carry out warm-rolling in the composite plate temperature, and its percentage pass reduction remains between 8% ~ 16%, carries out 4 ~ 7 passages altogether, and total working modulus is 55% ~ 65%; E, take apart through the combination of the composite plate of warm-rolling, individual composite plate is carried out cold rolling, percentage pass reduction is between 6% ~ 12%, carries out 3 ~ 7 passages altogether, and total working modulus is 12% ~ 26%; F, finishing, smoothing, cutting.
The diffusion welding method that the present invention prepares titanium aluminum composite plate has two kinds:
A kind of is diffusion welding (DW) under the vacuum pressure condition: in the compound process b of titanium sheet metal and aluminium sheet, the faying face that titanium sheet metal and aluminium sheet is compound is with the mechanical means polishing and clean out, put into vacuum tank then, stack between the titanium aluminum composite plate that carries out Diffusion Welding together in many groups, do not need the surface of welding, spreading has one deck nonmetallic materials barrier.In vacuum is 10
-2 -10
-5Pa maintains the temperature at 520 ~ 600 ℃, and pressure is 6 ~ 12N/mm
2Process conditions under, carry out vacuum diffusion welding and connect, it is 0.5 ~ 1 hour that vacuum diffusion welding connects the time; Naturally cool to room temperature then, open vacuum tank, take out titanium aluminum composite plate.
