Rapid Carburization of Cylindrical Parts Using a High Energy Electron Beam

Abstract:

Inthepresent paper wereporton surface alloyingof cylindrical substrateswithcarbonbynon-vacuumelectron-beamprocessing. A carbon fabric was used as a source of carbon. The electron-beam processing of the carbon fiber wrapped around the cylinders led to the formation of carbon-rich layer on the surface of the samples. Thehighestconcentrationofcarbonwasreacheddirectly on thesurface of the samples and was equal to ~4.3 % (wt.). The concentration of carbon gradually decreased to ~0.8 % (wt.) towards the substrate.The surface of the reinforced material had a high level of hardness (up to 750 HV). Wear resistance,underconditions of abrasive particleimpact, increased by 15% compared to wear resistanceof the sample produced by pack carburization and quenching.
