Abstract
The data on investigation of sample materials used for fabrication of medical implants (stainless steel 316L, and VT1-0 and CoCrMo (Wironit) alloys) are reported, which were subjected to surface treatment with the pulsed electron beam having the following parameters: pulse duration - 20-200 μs, energy density per pulse - 8-20 J/cm2, number of pulses - 1-5, and pulse repetition frequency - 0.3-1 Hz. A significant structure rearrangement is revealed, which is followed by changes in the modified surface layer properties of these materials. The surface roughness is found to decrease, while the corrosion resistance is improved; slight changes are also observed in the modified layer microhardness compared to the initial state.
