Abstract
Systems, methods, and devices for forming and implementing a graphene-copper composite powder are disclosed. The graphene-copper composite powder may be formed by providing an inert environment, introducing a first mist to the inert environment, introducing a second mist to the inert environment, and mixing the first mist and the second mist within the inert environment to thereby produce a graphene-copper composite powder. The first mist being atomized copper with a negative charge, and the second mist including graphene flakes with a positive charge. The graphene-copper composite powder may be used to form components via additive manufacturing or traditional powder metallurgy processes.
