Abstract
Abstract Currently, there is a worldwide search for new forms of materials with properties that are significantly improved in comparison to materials currently in use. One promising research direction lies in the synthesis of metals containing modern carbon materials (e.g., graphene, nanotubes). In this article, the research results of metallurgical synthesis of a mixture of copper and two different kinds of carbon (activated carbon and multiwall carbon nanotubes) are shown. Samples of copper–carbon nanocomposite were synthesized by simultaneously exposing molten copper to an electrical current while vigorously stirring and adding carbon while under an inert gas atmosphere. The article contains research results of density, hardness, electrical conductivity, structure (TEM), and carbon decomposition (SIMS method) for the obtained materials.
Highlights
COMMON metallic materials have a well-known set of basic properties
The mechanical properties of different base materials such as Cu, Al, Mg, Sn, Zn can be increased in various ways, e.g., by alloying materials with different elementary substances, by plastic working, heat treatment and thermo-mechanical treatment of obtained alloys
(2) It was found that obtained casts have density at the same level as Cu oxygen-free high conductivity (OFHC) base material
Summary
The mechanical properties of different base materials such as Cu, Al, Mg, Sn, Zn can be increased in various ways, e.g., by alloying materials with different elementary substances, by plastic working, heat treatment and thermo-mechanical treatment of obtained alloys. Those methods are well understood and commonly used all over the world. After the discovery of new carbon forms (graphene and carbon nanotubes), many researchers pursued the idea of combining them with metals.
