Composite metal-carbon nanoparticles attract great attention as a subject of research because of their well-known properties, such as good conductivity, antibacterial and catalytic effects, etc. There are various methods for obtaining composite metal-carbon nanoparticles, chemical, electrochemical, sonochemical, etc. In this work, a combined RF and magnetron discharge was used to obtain composite metal-carbon nanoparticles. According to the results of the experiments, it was found that an increase in the discharge current of the magnetron leads to an increase in the size of carbon-copper composite nanoparticles, as well as an increase in the thickness of nanostructured films. For the synthesis of composite carbon-copper nanoparticles, an argon-methane gas mixture (10%) was used. It was determined that increasing the gas pressure in the volume leads to a decrease in the size of the nanoparticles.
