Embodiment 1

[0036] Using copper (purity 99.8%), iron (purity 99.8%), cobalt (electrolytic cobalt, purity 99.8%) as raw materials, after ultrasonic cleaning, press Cu 50 Fe 50-x Co x (x=1-20at.%) components are weighed, and the preset mass of the sample is 15-20g. The weighed metal is smelted in a vacuum melting electric arc furnace under an argon atmosphere. In the arc smelting process, in order to make the alloy smelt uniform, the magnetic stirring function of the electric arc furnace is turned on, and the smelted alloy ingot is turned upside down and smelted more than 3 times. The smelted alloy is polished with coarse sandpaper to remove the oxide layer on the surface of the alloy, and cut into slices of appropriate size and thickness of 0.5mm. The cut slices are polished. Put the polished sample in alcohol and clean it in an ultrasonic cleaner for 10 minutes to remove oil stains on the surface of the sample, and then vacuum seal the sample into a quartz tube on the packaging table. In...

Abstract

The invention provides a highly-ordered single-piece copper-based porous material and a preparation method thereof and relates to a single-piece copper-based porous material. The preparation method comprises the following steps: preparing the raw materials of the single-piece copper-based porous material according to the atom ratios of Cu50Fe[50-x]Cox, Cu50Fe[50-x]Nix and Cu50Fe[50-x]Mnx, wherein x is 1-20at.%; smelting prepared alloys, starting a magnetic stirring button, and cooling after uniformly smelting; cutting a smelted Cu-Fe-X system alloy into slices by adopting a line cutting machine, carrying out thermal treatment after polishing, and quenching, wherein X is Co, Ni or Mn; pretreating a sample subjected to thermal treatment in a hydrochloric acid solution and then placing in an electrochemical workstation for electrochemical corrosion, wherein the alloy is connected with a positive electrode of a power supply, pure copper is connected with a negative electrode, and a sulfur acid solution is used as an electrolyte and placed in an electrochemical device; and cleaning the alloy subjected to electrochemical corrosion, and blow-drying so as to obtain a product. The single-piece copper-based porous material has the advantages of high order degree and controllable pore diameter size and distribution.

Description

Technical field [0001] The invention relates to a single piece of copper-based porous material, in particular to a single piece of copper-based porous material prepared by a dealloying method with orderly pore arrangement. By controlling the alloy composition and heat treatment process, the pores in the porous sheet material are realized The degree of order and transparency are controllable. Background technique [0002] Dealloying, that is, selective corrosion, refers to the large difference in electrode potential between alloy components, and the electrochemically active elements in the alloy selectively dissolve into the electrolyte under the action of the electrolyte, leaving the more stable element corrosion Process ([1] Tan Xiulan, Tang Yongjian, Liu Ying, etc. Dealloying to prepare nanoporous copper. Strong laser and particle beam 2009, 21(1)). The porous metal material prepared by the dealloying method has small and uniform pores. In recent years, it has attracted much a...
