In order to study physical features and technological capabilities of continuous optical discharge, a number of laboratory stands and plasmatrons were developed, which were used to determine the ranges of variation of energy, gas-dynamic, chemical and design parameters, providing stability of processing operations. It was found that at the change of power of CO2-laser radiation in the range of 1.5–6.0 kW, power of continuous optical discharge changes linearly, while power of laser radiation, passing through the discharge, can be regulated from 8 to 40 % of CO2-laser radiation power. Shown is the possibility of additional energy input into continuous optical discharge from direct current source. Here, power of additional input can exceed that of laser radiation. It is rational to apply continuous optical discharge, together with laser radiation which passed through it, to produce new materials, nanostructured carbide and diamond films, spheroidizing of refractory materials, surface modification, surfacing and other related technologies. 14 Ref., 1 Table, 3 Figures.
Keywords: continuous optical discharge, CO2-laser radiation, surfacing, heat treatment, experiments, modes, metallography, structure, residual stresses
