Electrolyte Plasma Modification of Surface of Al- and Ag-Based Alloys at Electro-Hydro-Dynamic Mode of Anodic Process

Abstract

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.

Plasma electrolytic processing of bimetals at the anodic process

“…Water solutions of salts are usually used to polish metals by PeP. For example, to treat Al or Ag can be used the water solutions of fluoride and citrate of ammonium at the electrolyte temperature of 60 ÷ 90°C [24].…”
