Study of Influence of Electron Beam Treatment on Surface Properties of the Material Produced by Selective Laser Melting

The treatment of solid surface by powerful streams of charged particles accelerated with power density ≥10⁶ W/cm² widely used for modification of different materials properties. The fast enter of electron beam power in the material of target causes the flow intense thermal and deformation processes. The changing of the structure, the phase composition, the microrelief of treated surface consequently happens. It is often accompanied by the hardening and increase of the wearing properties. The work proposed of using low-energy high-current electron beam as finish treatment of product obtained by selective laser melting of heat-resistant nickel alloy EP648. The subject of research was the surface properties of the product.
