Functional Surface Layer Strengthening and Wear Resistance Increasing of a Low Carbon Steel by Electrolytic-Plasma Processing

The modified technology for strengthening the surface layer of low-carbon steel machine components by electroplasma processing is proposed. This to be used as an alternative carburizing method with subsequent hardening. developed proposed based on author’s invention. parameters this process are given, resulting in a thickness reinforced 1000 µm 1700 µm. An increase microhardness 1.5 2 times (compared initial state) was observed. With hardening, chemical modification material’s occurs. microstructure treated samples characterised dark layer: fine needle-like structure martensitic origin under transforms into perlite-ferritic structure. advantage electrolytic plasma consists low energy consumption at high hardening speeds and possibility local areas, especially large parts complex shapes. In addition, treatment using (EPP) not only achieves smooth but also improves service qualities components, specifically wear resistance.
