Abstract
Apparatuses and methods for producing covetic materials by exciting a hydrocarbon gas with pulse microwaves to form hydrocarbon radicals in a hot first region of a microwave reactor. Graphene nanoplatelets are formed by the nucleation, growth and assembly of the hydrocarbon radicals, and contact a metal melt introduced downstream of the hot region to produce a mixture of molten metal and graphene nanoplatelets which assemble in-flight to form covetic materials. Graphene planes are infused in the metal matrix to achieve carbon loadings of at least 60%.
