Embodiment 1
[0037] In this example, see figure 1 , a preparation device for high-strength and high-conductivity copper-carbon nanotube composite materials under a magnetic field, mainly comprising an electroplating device and an electroplating auxiliary temperature control system, the electroplating device mainly consists of an electroplating tank 4, an electroplating tank cover 14, an anode 8, and a cathode 9 , power supply 11, inject electroplating solution 6 into the electroplating tank 4, arrange the anode 8 and the cathode 9 in the electroplating tank 4 in parallel, and make the anode 8 and the cathode 9 immerse in the electroplating solution 6, and the anode 8 and the cathode 9 also pass through the The wire is connected to the positive and negative poles of the power supply 11, the electroplating tank cover plate 14 seals the inner cavity of the electroplating tank 4, and the electroplating auxiliary temperature control system is mainly composed of a thermocouple 15, a heating devic...
Embodiment 2
[0048] This embodiment is basically the same as Embodiment 1, especially in that:
[0049] In the present embodiment, the power supply 11 is a pulse power supply with adjustable duty cycle and frequency, the copper strip and the anode 8 form an electrode system, and form a horizontal electrode system in which each electrode surface is in a horizontal direction, and the constant magnetic field generator 1 produces The direction of the magnetic field is the horizontal direction. The horizontal weak magnetic field vertical electrode system and the horizontal weak magnetic field horizontal electrode system are introduced into the preparation process of high-strength and high-conductivity copper-carbon nanotube composites, because the magnetic field direction, magnetic field strength and electrode orientation change The impact on the electrical and mechanical properties of the composite coating can prepare copper-carbon nanotube composite materials with better performance.
Embodiment 3
[0051] This embodiment is basically the same as the previous embodiment, and the special features are:
[0052] In this embodiment, under the premise that the dispersant polyacrylic acid exists, the auxiliary dispersant cetyltrimethylammonium bromide is added to further improve the dispersion effect of the plating solution, and it can also be applied to iron, nickel, aluminum or Composite electrodeposition preparation process of magnesium metal matrix.
