FIELD: chemistry.
SUBSTANCE: invention relates to application of coatings from disperse materials on inner surfaces of small size articles, in particular, to plasmatron for application of coating on inner surfaces of articles, and can be used in aerospace, aviation, metallurgical and other industries. Cathode and anode assemblies of the plasmatron are separated by an electrically insulating sleeve. Plasmatron comprises working gas supply and cooling systems with cooling channels. Anode assembly is made in the form of a nozzle, into which the tungsten insert is pressed. Cathode and anode assemblies have separate cooling systems.
EFFECT: cooling channels are formed by covers soldered to cathode and anode assemblies, respectively.
