Frequency AC plasma nitriding kinetics and its comparison of DC plasma nitriding

And layer depth were increased,[link widoczny dla zalogowanych], but the exchange of ion nitriding increased rapidly, as N. : H. ≥ 8:2, the AC and DC plasma nitriding of the differences disappear. 3. Temperature,[link widoczny dla zalogowanych], pressure, glow discharge current on the AC and DC plasma nitriding layer thickness of the same law. ● BIBLIOGRAP Island 68 Ⅱ ... PH · A ·, Ky3Ileqo at r.
