Plasma electrolytic oxidation is a powerful technique allowing the formation of ceramic coatings with high degree functionalization. Plasma–chemical interactions, resulting from application voltage in conductive electrolyte, like 0.5 M NaOH, favor development porous surface, which deserves to be sealed obtain proper corrosion resistance. In present work, effect temperature employed during seali...

Original scientific paper In the paper, the SEM and EDS study results of the surface coatings formed on the niobium and titanium alloys (TNZ, NiTi, Ti6Al4V) after the Plasma Electrolytic Oxidation (PEO), also known as Micro Arc Oxidation (MAO), are described. For the experiment of the PEO treatment, a non-conventional electrolyte, based on the concentrated orthophosphoric acid, was used. Copper...

Plasma electrolytic oxidation (PEO) is the new, environmentally and cost-effective method for coating the metals. This method vastly has been studied for coating Aluminum, Titanium and Magnesium and their alloys and recently for steel. In present study, Ck45 steel samples were coated by PEO method in order to improve corrosion resistance. During this process specimens were immerged in carbonate...
