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.
