Abstract

The structure and the phase composition of the diffusion saturation zone of 40Cr- and 12Cr2Ni4Ntype steels subjected to nitriding a low-pressure gas discharge plasma have been studied by the methods of optical, scanning, and diffraction electron microscopy. An essential possibility of nitriding steel at low (~200°С) temperatures has been revealed. The structural-phase state of the nitrided layer has been shown to depend strongly on the morphology and phase composition of the initial material.
