摘要

The present work is devoted research of influence of various modes of electrolyticplasma cementation on feature of change a structurally-phase conditions and hardening of a constructional steel 30CrMnSi. It is chosen scientifically proved low-power and resources-economy a processing kind which leads to formation stable ferrite-perlites structures, provides higher mechanical properties. Cementation process carried out with selection of different modes of electrolytic-plasma processing in the electrolyte containing water solution of 10% of sodium carbonate and 10% of glycerin. As the basic methods of research in work we used metallographic the analysis with microscope application "NEOPHOT-21", X-ray analysis on diffractometer X'PertPRO in monochromatic CrK_α - radiation, tests for microhardness for device PMT-3. It is established that a microstructure of samples steel 30CrMnSi at different modes of processing consist from α - phases, particle carbides and retained austenite. Microhardness of the initial sample makes approximately 3000 MPa, and after processing its microhardness makes 6100 MPA that speaks about of a processing mode. The developed technology of electrolytic-plasma cementation of constructional steels in the conditions of the arc category in electrolyte is the optimal as provides reliable quality and demanded properties of details, working in variable loadings and often exposed to wear, forms the strengthened, modified surface coating.
