Abstract: Corrosion results in short- or long-term deterioration of materials. All over the world, researchers and engineers try to find better and better resolution to inhibit these undesired processes. One of the very efficient techniques, when the metal surface is covered by nanolayers, that can control the corrosion, is the deposition of solids by metal layers with predefined characteristics (composition, thickness, etc.) Among the many electrochemical processes, we have applied the non-stationary electrochemical method, named pulse current electrochemical deposition (PC-technique) for nanostructured thin layers deposition. Applying a current interruption method, we produced pure metal and alloy coatings with various compositions and layer thickness developed from aqueous solutions, at ambient temperature. The exceptional advantage of pure metal coatings produced by PC technique is the pore free, nano-sized structure. All technical details are summarized in this paper and the anticorrosion efficiency of the nanocoatings is demonstrated, too.

Keywords: pulse current electrochemical deposition, metal (Fe, Ni) and alloy (Ni–Co, Fe–P) coating, anticorrosion activity
