Problems solved by technology

The preparation methods of titanium-copper composite materials that have been applied now require higher temperatures. If the gas protection or vacuum insulation equipment is not precise, titanium metal starts to absorb hydrogen at 250 ° C, oxygen at 400 ° C, and nitrogen at 600 ° C. The final connection will be brittle; on the contrary, the precision equipment will increase the cost
In addition, low melting point eutectics are easy to form under high temperature conditions, the tendency of hot cracking is greater, the thermal stress is higher, and the energy consumption is high, and it is easy to generate waste slag and waste gas

Embodiment 1

[0030] Take out the 0.2mm Ti foil, 0.1mm Cu foil and 0.015mm aluminum foil, and simply scrub the surface with alcohol to remove the oil on the surface of the material. Taking "Cu foil-Al foil-Ti foil" as a unit, the Ti foil is on the upper layer during consolidation, and a sample containing 5 units is prepared with a thickness of 1.5mm (ignoring the thickness of the aluminum layer), figure 1 for its schematic diagram.

[0031] After pre-treatment, the material is subjected to ultrasonic consolidation processing: at a temperature of 170°C, a consolidation pressure of 2205N, an amplitude of 40μm, and a consolidation speed of 10mm / s are used for consolidation preparation. By adding the aluminum layer, not only the connectivity of copper and titanium is improved, but also the copper layer is buffered to a certain extent to prevent the copper layer from being broken due to excessive pressure.

Embodiment 2

[0035] The raw materials and processing methods are kept unchanged, and titanium-copper layered electrode composite materials with different layer thickness ratios are prepared. Consolidate a layer of titanium foil first, adopting the following process parameters: the consolidation pressure is 2000N, the amplitude is changed to 35μm, and the consolidation speed is 25mm / s; then six layers of copper foil are consolidated. The intermediate transition layer metal aluminum foil is added between the materials, and the process parameters adopted are: the consolidation pressure is 1764N, the amplitude is changed to 30μm, and the consolidation speed is 25mm / s; finally, a layer of titanium metal foil is consolidated, and the process parameters are the same as the first same layer, image 3 for its schematic diagram.

[0036] The metallographic photograph (copper and self-solidification) of the layered electrode composite material that the present embodiment makes is as follows Figure...

Embodiment 3

[0038] The raw materials and processing principles adopted remain unchanged. The intermediate transition layer was changed to two layers of metal aluminum foil, and the same consolidation parameters as in Example 1 were adopted. The metallographic photograph of the composite material prepared in this embodiment is shown in FIG. 5 .

Abstract

The present invention provides a rapid preparation method of a titanium copper lamellar electrode composite material, which comprises the steps that: (1) copper foils, aluminum foils and titanium foils are superposed to form unit bodies, and one unit body is put on an ultrasonic quick-consolidating moulding work table; (2) an ultrasonic quick-consolidating moulding work table substrate is pre-heated to a temperature between 50 DEG C and 200 DEG C, and consolidating preparation is started and a metal foil material is formed; (3) the next unit body is put on the metal foil material, and the consolidating preparation is carried out by using the same parameters with the step (2) and the metal foil material is formed; and (4) the step (3) is repeated and after a predetermined thickness is reached, corner waste materials are milled and removed and the titanium copper lamellar electrode composite material is obtained. The titanium copper lamellar electrode composite material is prepared in the low temperature and is energy saving and environment-friendly. The cost of the raw materials is low. The titanium copper lamellar electrode composite material is prepared through solid-state physical metallurgical bonding. Diffusion layers are thin and by-products are few. The equipment cost is low because no vacuum devices or gas protection devices are used. The production period is short and the production efficiency is substantially improved. The precision and the yield are high.

Description

technical field [0001] The invention relates to a preparation method of a composite material. Specifically, it is a method for preparing titanium-copper layered electrode composite materials by using ultrasonic rapid consolidation forming technology. Background technique [0002] In the domestic chlor-alkali industry, the traditional graphite and lead-containing inert anodes have been gradually transitioned to the use of titanium inert anodes, which has greatly broken through the limitations of the traditional electrodes' heat generation, harmful impurities, low strength and short service life caused by corrosion resistance, greatly Promote the output of my country's chlor-alkali industry. However, the titanium inert anode has a big defect - high resistance, which restricts the further development of the chlor-alkali industry. [0003] In order to solve the problem of large resistivity of titanium inert anodes, people use the method of composite materials to combine copper ...
