Embodiment 1

[0033] A method for preparing a carbon nanoparticle solution, comprising the following steps:

[0034] Step 1, prepare electrolyte, the solute of the electrolyte is 0.15~0.25mol / L HNO 3 , 0.08~0.12mol / L (CH 2 Oh) 2, 0.15~0.25g / L C 12 h 25 NaSO 4 , the solvent is deionized water;

[0035] Step 2, take two high-purity graphite plates, clean them with deionized water, fix them with crocodile clips with copper rods, and fix them on the fixtures in parallel and vertically, and then put the fixtures into the electrolyte tank In the container, adjust the height of the fixture so that the graphite plate is immersed in the electrode solution, and then put the device into the ultrasonic instrument. After fixing, connect the positive and negative poles of the DC power supply to the copper rods respectively. After energizing and reacting, a carbon nanoparticle solution is obtained. ;

[0036] Wherein, the specification of the high-purity graphite plate in step 2 is 100*50*2mm.

Embodiment 2

[0040] Add carbon nanoparticle solutions with concentrations of 5mL / L, 10mL / L, 20mL / L, 30mL / L, and 50mL / L to the nickel plating solution respectively, and the prepared samples are recorded as the second sample, the third sample, and the fourth sample respectively. sample, fifth sample and sixth sample. Tested with the sample prepared above, its performance was analyzed, and 6 samples were obtained, and the performance analysis and comparison of these 6 samples were carried out. The results are as follows: Figure 3-6 shown.

[0041] It can be seen from the figure that when the concentration of the carbon nanoparticle solution is 10mL / L, the hardness, friction and wear resistance, and corrosion resistance of the coating are significantly improved, but the concentration of the carbon nanoparticle solution in the electroplating solution exceeds 10mL / L It will lead to the loose structure of the nickel coating, which will lead to the decline of its comprehensive performance. When...

Description

technical field [0001] The invention relates to the field of nickel coatings, in particular to a method for preparing a carbon nanoparticle solution and its application in nickel coatings. Background technique [0002] Nickel coating has high hardness, certain corrosion resistance and friction resistance, and has a beautiful metallic luster, so it is widely used in the fields of mechanical parts, electronic products and daily metal products. With the advancement of industrial technology and people's demand for high-performance products, ordinary nickel coatings are increasingly unable to meet performance requirements, and their hardness, wear resistance, and corrosion resistance need to be further improved. In recent years, researchers have increased the research on the performance improvement of nickel coatings. The composite coating formed by co-deposition of nano-hard particles and nickel has become a research hotspot in recent years. This process can improve the performa...
