The preparation and properties of zeolite-containing oxide coatings obtained by plasma electrolytic oxidation are investigated discussed. Pure Ce-exchanged natural (clinoptilolite) synthetic (13X) zeolites immobilized on aluminum support from silicate-based electrolyte. Obtained characterized with respect to their morphology, phase chemical composition, photocatalytic activity anti-corrosion pr...
Titanium dioxide-nickel oxide porous coatings were synthesized by Plasma Electrolytic Oxidation (PEO)/ ElectroPhoretic Deposition (EPD) in one step and within a short time. The main purpose of this research was to increase photocatalytic activity of titanium oxide by increasing surface area and coupling of titanium oxide with nickel oxide. Applied voltage effects on phase structure, surface mor...
In this study, Plasma Electrolytic Oxidation (PEO) technique was used for generating ceramic layer on the surface of aluminum alloy AA2024-T6 and the effect of coating time on the electrochemical corrosion behavior, micro-hardness, morphology of coating, and the phase structure was studied. The alloy was coated in 1, 3, 5 and 7 minutes at a constant electrical potential 550 V in a sodium silica...
In this paper, titanium oxide coating (TiO2) was produced on titanium alloy Ti6Al4V by Plasma Electrolytic Oxidation (PEO) Method. Sodium Silicate (Na2SiO3) and Sodium Aluminate (NaAlO2) based electrolytes were selected in PEO process. The effects of concentration of Sodium Aluminate (0, 2.5, 5, 7.5, and 10 g/L) on the microstructure and acoustical behaviour of the formed coatings were studied....
In this work, composite fluoropolymer-containing coatings were obtained on samples of AMg3 aluminium alloy, MA8 magnesium and VT1-0 commercially pure titanium treated by plasma electrolytic oxidation (PEO). Superdispersed polytetrafluoroethylene (SPTFE) a solution tetrafluoroethylene (TFE) telomers in acetone applied onto preliminarily formed PEO layers the spray-coating method. The contained l...
Plasma electrolytic oxidation (PEO) coatings on AZ91 Mg alloy were sealed in calcium nitrate solutions at different pH values (3, 4 and 5). Sodium dodecyl sulfate (SDS) was added to study the effect of SDS corrosion resistance coatings. The microstructure, chemical composition investigated by means SEM, XPS, XRD electrochemical tests. performance improved due precipitation Ca-containing precipi...
In this study, Plasma Electrolytic Oxidation (PEO) at three frequencies of 500, 1000 and 3000 Hz was applied on Mg surface and the effect of PEO surface preparation on protective behavior of three types of epoxy, fusion bond epoxy (FBE) and polyurethane coatings was investigated. The microstructural and protective properties of PEO coatings were studied by SEM, potentiodynamic polarization and ...

Plasma Electrolytic Oxidation (PEO) and Hard Anodizing (HA) coatings are investigated on an Additively Manufactured (AM) Al10Si1Mg alloy obtained via Direct Metal Laser Sintering (DMLS). Results compared to those for a conventional A361 cast alloy. Findings revealed that the microstructure of AM alloy, consisting α-Al cells enclosed in Si network, produces more uniform –in terms morphology, thi...
