原始语种摘要: The results of a complex study of the destructive effect of a nitrogen plasma jet at atmospheric pressure onto the surface of the MPG-6 graphite are presented. The space-time changes in the rate of decrease in the samples material, the temperature of their surface, the electron temperature of plasma in the oncoming flow and the plasma composition in the region of ‘injection’ were all experimentally determined. Using spectroscopic methods with high spatial (50 μ m) and time (0.5 s) resolutions changes in the concentration of emitting carbon atoms (line CI 247.9 nm) and CN (transition B2Σ+ − X2Σ+) near the surface of isotropic graphite were recorded, which occur in the process of intense and long (100–150 s) exposure of graphite to a nitrogen...
