Conclusions

Electron microscopical investigations have established that during “finish” ESA in air with transition metal carbides the surface of type U8 steel acquires a heterogeneous structure whose character depends on the duration of treatment and the physicochemical properties of the alloying carbide. A weakening of the homopolar component of atomic reaction in a carbide decreases the contribution from brittle fracture to its erosion, promoting the formation of a smoother surface microrelief with predominant participation of liquid phase.
