Abstract
Istota sposobu jarzeniowego azotowania wewnętrznych powierzchni tulei, zwłaszcza luf, w którym obrabiany przedmiot stanowiący katodę umieszcza się w próżni od 1 do 1500 Pa i łączy z dodatnim biegunem stałego napięcia wyładowania jonizującego o wartości 300 - 2000 V a do wnętrza obrabianego przedmiotu wprowadza się rurową anodę korzystnie z otworami dla przepływu atmosfery reakcyjnej stanowiącej mieszaninę wodoru i azotu, polega na tym, że jednocześnie na całą lub wybrane części obrabianej powierzchni katody (K) działa się polem magnetycznym o indukcji większej od 25 mT, przy czym źródło tego pola magnetycznego korzystnie umieszcza się wewnątrz anody i intensywnie chłodzi się go, ponadto, o ile wyładowanie jarzeniowe nie zapewnia wymaganej temperatury azotowania, obrabianą powierzchnię katody (K) dogrzewa się korzystnie promieniowaniem podczerwonym.The essence of the method of glow-discharge nitriding of the inner surfaces of the sleeves, especially the barrels, in which the cathode workpiece is placed in a vacuum from 1 to 1500 Pa and connected to the positive pole of a constant ionizing voltage of 300 - 2000 V and a tube anode is introduced into the workpiece preferably with holes for the flow of the reaction atmosphere consisting of a mixture of hydrogen and nitrogen, consists in the fact that at the same time the whole or selected part of the cathode (K) surface is treated with a magnetic field with an induction greater than 25 mT, the source of this magnetic field preferably being placed inside the anode and it is intensively cooled, moreover, unless the glow discharge provides the required nitriding temperature, the treated cathode surface (K) is preferably heated with infrared radiation.
