Abstract
Two plasma-chemical systems, namely air low-temperature and air-vapour plasma, are considered. In keeping with the kinetic diagram, including 258 reactions, the design method was used to determine the composition of the gas phase in weight fractions of the components.
Keywords: air-plasma cutting, plasma-forming medium, air-vapour plasma, plasma components, saturation with nitro¬gen, pore formation
