- Abstract
Tribotechnical characteristics of nitrided steels of pearlitic (38Kh2MYuA) and martensitic (16Kh2N3MFBAYu-Sh and 13Kh3N3M2VfB-Sh) classes are studied. The relation between the preliminary treatment of the steels and the structural and phase characteristics of the nitrided layer and its operating capacity under contact deformation, friction and wear is analyzed. It is shown that preliminary tempering after the quenching and subsequent surface or volume plastic deformation raise substantially the tribotechnical properties of the nitrided layer. The tribotechnical parameters of the steels are elevated by a combined heat, deformation and thermochemical treatment creating a fine structure under the deformation and activating the process of diffusion saturation under ion-plasma nitriding.
