Phase Composition and Microhardness of Surface Layers 34CrNi1Mo Steel after Electrolytic-Plasma Processing

Abstract:

Present work is devoted to phase composition research, structure and microhardness of structural steel 34CrNi1Mo after electrolytic-plasma processing in a cathode heating mode. Technology of electrolyte-plasma hardening provides reliable quality and the required mechanical properties of the products which are often subjected to wear and temperature-force actions. Results of microscopic researches and X-ray structure analysis are presented in this work. It is established that microstructure of steel detail modified layer being processed in electrolytic plasma at a temperature of 850 °C during 5 minutes, is generally represented by martensite quenching. The phase composition of steel 34CrNi1Mo after electrolytic-plasma carburization is presented by structure of α-Fе phase and carbide phases Fe₂C, Fe₃C. Surface microhardness increases more than by 2.5 times in comparison with a reference value.
