Avinit duplex technologies have been developed, combining N plasma nitriding of finished high-precision parts with subsequent application superhard antifriction coatings in a single technological process Due to the absence brittle layer on nitrided surface after precision nitriding, preservation original geometric dimensions that do not require further mechanical refinement, and compatibility p...

The paper shows the prospects of nitriding in a cyclically switched discharge, classification processes glow discharge according to criteria characteristics power source is given. A comparison advantages and disadvantages with constant given.From theoretical point view, process considered based on concept an energy model. In accordance this model, tasks for further experimental research are for...
