The plasma-jet heat treatment of the gas-thermal coatings

The object of investigation: the electric-arc plasmic generator (plasmotron). The purpose of the work: the development and investigation of the laminar plasmotron and optimization of the technology of the plasma-jet thermal treatment of gas-thermal coating. The parameters of the plasmic jets have been studied with the aid of the enthalpy probe and by means of the spectral measurements. The heat exchange has been studied with the aid of the thermal stream transmitter. The peculiarities of formation of the plasma jets and its heat exhange with the obstruction with small numbers of Reinolds have been studied. The dependence of formation of "steel - coating" composite structure on the temperature-temporary parameters of the treatment process has been determined. The plasmotron intended for the thermal treatment has been created, and the optimization of the technology of the plasmic-jet treatment of the gas-thermal coating has been performed. The plasmotron and the plasmajet thermal treatment technology have been introduced in the REB fleet. The efficiency of introduction: increase in capacity of the thermal treatment and decrease in zone of the thermal effect in partsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
