Embodiment 1
[0043] This embodiment is a method for preparing a copper coating on a carbon fiber surface to improve the carbon / magnesium composite interface and its wettability.
[0044] The concrete steps of this embodiment are:
[0045]Step 1: Put the carbon fibers in acetone and stir for 16 hours, take out and ultrasonically clean them with deionized water for 15 minutes to obtain degummed fibers; then put the degummed fibers in a sodium hydroxide solution with a concentration of 150 g / L, and the water bath temperature is 50 ℃, the time is 1.0h, after taking it out, wash it with deionized water for 5 minutes to obtain the coarsened fiber; then put the coarsened fiber into the mixed solution of stannous chloride and hydrochloric acid with concentrations of 5.0g / L and 30ml / L, respectively, The treatment temperature is 15°C, the time is 5min, and the sensitized fiber is obtained by washing with deionized water for 5min after taking it out; then the sensitized fiber is placed in a mixed sol...

[0050] This embodiment is a method for preparing a copper coating on the surface of carbon fiber which improves the interface of carbon / magnesium composite material and its wettability.
[0051] The concrete steps of this embodiment are:
[0052] Step 1: Put the carbon fibers in acetone and stir for 20 hours, take out and ultrasonically clean them with deionized water for 25 minutes to obtain degummed fibers; then put the degummed fibers in a sodium hydroxide solution with a concentration of 200 g / L, and the water bath temperature is 65 ℃, the time is 2.0h, after taking it out, wash it with deionized water for 7min to obtain the coarsened fiber; then put the coarsened fiber into the mixed solution of stannous chloride and hydrochloric acid with concentrations of 10g / L and 40ml / L, respectively, to treat The temperature is 25°C, the time is 12min, and the sensitized fiber is obtained by washing with deionized water for 7min after taking it out; then the sensitized fiber is place...
Embodiment 3
[0057] This embodiment is a method for preparing a copper coating on the surface of carbon fiber which improves the interface of carbon / magnesium composite material and its wettability.
[0058] The concrete steps of this embodiment are:
[0059] Step 1: Put the carbon fibers into acetone and stir for 24 hours, take out and ultrasonically clean them with deionized water for 30 minutes to obtain degummed fibers; then put the degummed fibers in a sodium hydroxide solution with a concentration of 250 g / L, and the water bath temperature is 80 ℃, the time is 3.0h, after taking it out, it is washed with deionized water for 10min to obtain the coarsened fiber; then the coarsened fiber is put into the mixed solution of stannous chloride and hydrochloric acid with concentrations of 15g / L and 50ml / L respectively. The temperature is 35 °C, the time is 20 min, and the sensitized fiber is obtained by washing with deionized water for 10 min after taking it out; then the sensitized fiber is ...
