Structural-phase state of the surface layer of low-carbon steel after electrolytic-plasma modification
An alternative technology of strengthening by electrolyticplasma modification of lowcarbon alloy steel for the wedge columns binding for stop valves has been developed. The processing of steel 20X samples was carried out on an experimental installation, the optimal processing modes were determined experimentally. Simulation of the treated surface makes it possible to assume that during the electrolyticplasma heating of parts, along with quenching, chemical modification of the metal surface layers occurs. The volttemperature characteristic with the superposition of real time on the proposed processing clearly shows a significant reduction in the time for hardening, relative to traditional hardening methods of similar steel. Also, energy consumption and, accordingly, the cost of the part and the product as a whole are significantly reduced. Electrolyteplasma modification promotes the transformation of coarsegrained pearliteferrite microstructure into quenched martensite. An increase in hardness relative to the initial state indicates an increase in physical and mechanical properties after electrolyteplasma treatment. The advantage of the method of electrolyticplasma treatment consists in low energy consumption at high quenching rates, the possibility of local surface treatment; there are prerequisites for creating a semiindustrial installation for an alternative electrolyteplasma hardening.
