“…During the MAO either galvanostatic mode (the current density is maintained constant) or potentiostatic mode (the voltage is maintained constant) are usually in use. [1][2][3][4][5][6] During electrolyte-plasma processing (EPP) the current density is set automatically and persists be practically constant as for electrolytic-plasma heating (EPH) as for electrohydrodynamic (EHD) process for any voltage inside the mode. So, terms "galvanostatic mode" or "potentiostatic mode" cannot be used for EPP.…”

“…Authors [1][2][3] determine the micro-arc oxidizing (MAO) as electrochemical process of the surface modification (oxidation) of valve metals (Al, Mg, Ti, Zr, Nb, Ta, W, etc.). The nature of MAO is that migrating electric discharges form an oxidized layer on the object surface, which serves as one of the electrodes of the electrolytic cell.…”

This article briefly reviews modern methods for oxidizing coating of valve metals (Al, Ti, Mg, etc.). These methods include microarc oxidation, plasma-electrolytic-arc oxidation, anodic -spark oxidation. Their common characteristics as well as differences between these methods and electrolyte-plasma processing by electrohydrodynamic mode of anodic process are described. The composition, microstructure and surface morphology of the coating formed on the surface of titanium alloys depending on the electrolyte-plasma processing parameters are investigated.

Electrolyte plasma processes are advanced high-effective and ecological methods of treating the metal surface and can be used as for cleaning and polishing of metal surfaces, as for thermochemical treatment. Previously we showed the possibility to prepare coatings on valve metals at the electro-hydro-dynamic mode and described some patterns of this process. This article is dedicated to the description of coating of both valve and non-valve metals and alloys. Composition, structure and morphology of coatings, which are forming on the Ag-and Al-based alloys surface, were studied depending on parameters of the electrolyte plasma processing.
