Abstract

The ESD method (electro spark deposition) is used to cover through deposition the active parts of machines, working in heavy abrasive wear moist environment as well as in a dry environment. The paper proposes the use ESD method for Fe-C alloys for obtaining thin layers system with physical-mechanical properties improved comparing to base material. Due to polar effect, the predominant transfer of anode’s material (electrode) towards cathode (piece) assures the forming of the superficial layer with well-determined physical - chemical properties. In addition, in multiple layers case the deposit of a supplementary layer emphasizes the diffusion of the first deposited layer by anchoring more the coating.
