Abstract

Results are given of a study of the production of nitrided layers on 33H3MF steel and Armco iron in a pulsed plasma excited at a frequency between 10 and 60kHz in N2 + H2 mixture. The transistorized voltage supply unit used was the only source of input energy and no additional resistance heating was employed. The layers obtained were examined metallographically and by X-ray techniques. The microhardness profiles, corrosion resistance and wear resistance of the layers were also examined. The increased operating frequency of the glow discharge allowed nitriding in component openings of 2–10 mm in diameter (minimum) and 20 mm deep, which was not possible with a direct current glow discharge. The layers produced appeared to be highly resistant to corrosion and frictional wear.
