Abstract
High-temperature interaction of 30 wt % Cu–70 wt % Ag eutectic alloy with carbon fibers was studied. It was shown that Cu–Ag drops coated with carbon film are formed on the surface of carbon fibers. Carbon atoms dissolved in the molten Cu–Ag phase precipitated out on the drop surface at a lower temperature, thus resulting in growing few-layer graphene. Cu–Ag–carbon fibers composites sintered at 670°C was shown to represent a porous structure containing spherical Cu–Ag particles and carbon fibers. It was revealed that as C is added, the electrical resistivity of sintered samples decreases. Raman spectra of sintered composites containing 3.0 and 6.3 wt % C showed the formation of a multilayer graphene coating with a disordered structure.
期刊介绍:
International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
