摘要：
The article presents a characterisation of nitrided layers produced on austenitic X2CrNiMo17-12-2 (AISI 316L) stainless steel in the course of glow-discharge nitriding at cathodic potential, at plasma potential, and at cathodic potential incorporating an active screen. All processes were carried out at 440 degrees C under DC glow-discharge conditions and in 100 kHz frequency pulsed current. The layers were examined in terms of their microstructure, phase and chemical composition, morphology, surface roughness, hardness, wear, and corrosion resistance. Studies have shown a strong influence of the type of nitriding method used and of the electrical conditions on the microstructure and properties of the diffusion layers formed.
