This paper reports on nitriding of low-alloy steel samples which are placed outside the plasma and exposed only to the effect of activated nitriding gas diffusing from a low-pressure microwave discharge with electron cyclotron resonance (ECR). It is shown that efficiency of nitriding of the samples located inside the discharge (i.e. at a standard distance d=250 mm from the output aperture of the ECR...
The paper reports on a new system for plasma nitriding combined with a hollow cathode discharge sputtering at high pressures (about 1000Pa), a new way of producing duplex coatings, and on a low-pressure (0.1-0.3Pa) plasma nitriding using microwave discharges. It has been shown that an addition of an auxiliary cathode into a conventional high-pressure nitriding system can improve properties of the...
