Problems solved by technology

In the existing graphene-enhanced aluminum alloy preparation process, due to the uneven dispersion of graphene, agglomeration is prone to occur; secondly, after graphene is added, the wettability of the aluminum alloy substrate is checked, and the interface between the two is not ideal, so that the graphene enhancement effect is not good. Ideal, can not meet the industrial production needs of aluminum alloy wire, limit the development and application of material technology
