The method of electric discharge treatment of carbon-containing gases [1] allows to obtain a nanostructured coating of almost the same size particles that form micrometer globules. Nanocarbon coating has no impurities. Particle sizes is no more 40 nm. This coating is X-ray amorphous and attenuates X-rays at wavelength
= 0,154178 nm on average by 51%.
Electric discharge through a metal conductor in carbon-containing gas [2] allows to obtain a nanostructured composite coating, which consists of carbon, metal and carbide globules and is uniform in particle size. The particle sizes obtained from tungsten wires are 40 nm, and from titanium wires - 100 nm. The hardness of the substrate surface is significantly increased due to the applied coating.
