Abstract
The paper studies the effect of pulse plasma treatment on the physical and mechanical properties of 40Kh steel. The structural and phase changes were studied in the surface layers using metallographic and X-ray phase analysis. Cyclic action and high heating and cooling rates in the surface layers lead to a change in the kinetics of phase transformations, generation of inhomogeneous distortions of the crystal lattice as a result of phase strain hardening, a decrease in the dispersion of the structure, formation of an increased dislocation density, etc. Tribological tests for wear resistance were carried out under fluid friction conditions at various loads and sliding speeds. Comparative data on the extent of linear wear and wear intensity of the test samples were obtained.
Keywords: pulse plasma treatment, structural alloy steel, structural phase analysis, hardness, microstructure, friction pair, wear
