[0026] like figure 1 As shown, a method for preparing a corrosion-resistant aluminum-carbon composite material according to an embodiment of the present invention includes the following steps:
[0027] Step S1: under the protective atmosphere of argon, the graphene, the aluminum powder and the process control agent are mixed and ball-milled, and after heating and heat preservation, the aluminum-carbon composite powder is obtained;
[0028] Step S2: After the aluminum-carbon composite powder is rotationally extruded and held by large plastic deformation, a corrosion-resistant aluminum-carbon composite material is obtained.
[0029] In the embodiment of the present invention, graphene, aluminum powder and process control agent are mixed and ball-milled, and then the aluminum-carbon composite powder is rotationally extruded and held by large plastic deformation, so that graphene is broken and peeled off in the aluminum matrix. , redistribute, realize super-homogeneous distributi...
Embodiment 1
[0049] In the present embodiment, the corrosion-resistant aluminum-carbon composite material is prepared by the preparation method of the corrosion-resistant aluminum-carbon composite material, and the specific steps are as follows:
[0050] Step S1: weigh 0.3 g of thin-layer graphene nanosheets and 19.7 g of 1060 industrial pure aluminum powder in a high-purity argon-protected glove box (water and oxygen < 0.01 ppm), put them into a vacuum-sealed stainless steel ball mill, and then place them in a vacuum-sealed stainless steel ball mill. The stainless steel ball milling jar is sealed in the glove box and taken out for ball milling, and then placed under the protection of high-purity argon and heated to 450 ° C and kept for 0.5 h, until the process control agent is completely volatilized, and the pre-mixed aluminum-carbon composite powder is obtained; among them, graphite The number of layers of the alkene nanosheets is 5-15 layers, the average particle size of the pure aluminu...
