Fabrication and Cold Drawing of Copper Covetic Nanostructured Carbon Composites/ Otrzymywanie Oraz Ciągnienia Kompozytów Miedzianych Typu Covetic O Strukturze Nanometrycznej

Abstract: This paper presents the research results of copper Covetic metallurgical synthesis along with the characterization of cast material and the processing of casts into wires. The Cu-C composite production method was based on patent applications of Third Millennium Metals. Obtained materials were tested for their chemical composition (including Secondary Ion Mass Spectrometry (SIMS) analysis for carbon presence), mechanical properties and electrical conductivity. Measurements were also performed for wires which we… Show more

“…At elevated temperatures of 800 °C or higher, the carbon first diffuses in copper along the {111} plane until it reaches saturation. , After that, carbon precipitation to the surface occurs by back diffusion , during cooling at temperatures typically below 800 °C. The Raman analysis help in understanding the back-diffusion process, supporting the idea that carbon has a greater tendency to precipitate along the terraces, mainly the {110} and {100} planes toward the {111} planes where it concentrates and orders the graphene sheets.…”
