Abstract
Through electron-beam surfacing of tungsten or chromium carbides on an electron accelerator followed by pulsed treatment with low-energy electrons, a nano- and superfine grain structure with a system of nanodimensional pores is fabricated. The nanohardness and modulus of elasticity are shown to be extremely high in the zone of secondary pulse action. The modified surface layer having a nanostructure and chaotically distributed pores may be a barrier to brittle fraction.
