Embodiment 1

[0022] A preparation method of diamond and carbon nanotube fiber composite material, comprising the following steps:

[0023] (1) Take a certain amount of diamond and a certain amount of solvent, and make the diamond evenly disperse to form a diamond solution 2 by means of ultrasonic dispersion; specifically, the particle size of the diamond is between 0.5 μm and 10 μm, and the carbon nanotube fiber The diameter is between 100 μm and 200 μm, and the length of the carbon nanotube fibers is between 0.5 cm and 10 cm. The solvent includes water and alcohol. The concentration of the prepared diamond solution 2 is between 0.0005wt.% and 0.01wt.%.

[0024] (2) With the carbon nanotube fiber as the positive pole and the stainless steel plate as the negative pole, the diamond is evenly adhered to the surface of the carbon nanotube fiber by the electrophoretic co-deposition method; specifically, the voltage used by the electrophoretic co-deposition method is 2V To 30V, the deposition ...

Embodiment 2

[0030] The difference between this embodiment and embodiment 1 is that each parameter is different, specifically as follows:

[0031] Take 4 cm of diamond powder with a particle size of 3 μm and carbon nanotube fibers with a diameter of 100 μm. Diamond powder was weighed by an electronic balance, and added to 100 ml of alcohol solution to prepare a diamond solution 2 with a concentration of 0.001 wt.%, and ultrasonically dispersed in the diamond solution 2 for 10 minutes. The carbon nanotube fiber is used as the positive electrode, the 304 stainless steel is used as the negative electrode, the DC voltage is 10V, and the time is 20s. Through the electrophoretic co-deposition method, the diamond is uniformly adhered to the surface of the carbon nanotube fiber. Take out the carbon nanotube fiber stuck with diamond, put it into a high-frequency induction sintering furnace after drying, and turn on a current of 60A for 50s under argon protective gas to obtain a diamond carbon nanot...

Abstract

The invention provides a preparation method of a diamond and carbon nanotube fiber composite material. The preparation method comprises the following steps: (1) acquiring diamonds and a solvent of certain mass, and dispersing the diamonds uniformly by way of ultrasonic dispersion to form a diamond solution; (2) attaching the diamonds uniformly to the surfaces of carbon nanotube fibers by means ofelectrophoresis codeposition by taking the carbon nanotube fibers as an anode and a stainless steel plate as a cathode; and (3) putting the carbon nanotube fibers with uniformly attached diamond particles into a high frequency induction furnace, and making current to cure and sinter the diamonds and the carbon nanotube fibers to obtain the diamond and carbon nanotube fiber composite material. Thecomposite material obtained by the technical scheme not only has high hardness of the diamonds, but also has high strength and high toughness of the carbon nanotube fibers.

Description

technical field [0001] The invention relates to a preparation method of diamond and carbon nanotube fiber composite material. Background technique [0002] The combination of traditional diamond and ordinary fiber is mainly realized by binder, and the obtained fiber diamond tool can be used in the processing of metals, alloys, ceramics, semiconductor devices, etc. However, the diamond on the fiber surface of the tool has poor dispersion, is easy to agglomerate, and has insufficient holding force, and the ordinary fiber has poor toughness and is easy to break, resulting in short service life and poor processing effect of the final tool. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of preparation method of composite material of diamond and carbon nanotube fiber, make the obtained composite material not only have the high hardness of diamond but also have the high strength a...
