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...

Effects of alloying element Ca on the corrosion behavior and bioactivity of films formed by plasma electrolytic oxidation (PEO) on AM60 alloys were investigated. The corrosion behavior was studied by conducting electrochemical tests in 0.9% NaCl solution while the bioactivity was evaluated by soaking the specimens in simulated body fluid (SBF). Under identical anodization conditions, the PEO fi...

Plasma Electrolytic Oxidation (PEO) was applied to extruded ZM21 Mg alloys improve their corrosion resistance in a chloride-containing environment. PEO carried out DC mode and voltage control fluoride-free electrolyte. Potentiodynamic polarization tests 3.5 wt.% NaCl aqueous solution neutral salt spray (NSS) were out. Microstructural profilometric characterization, as well NSS performed differe...

Plasma electrolytic oxidation (PEO) was performed on a 1010 Aluminum alloy. To achieve thenanocomposite structure, Si3N4 nanoparticles were added into the electrolyte. In an alkaline aqueoussuspension (silicate-based), the effect of adding NiSO4 on the applied voltage, microstructure,composition, wear, and corrosion resistance of PEO coatings was investigated using ScanningElectron Microscopy (...

In this paper, the surface modification of titanium alloys Ti-15Mo, Ti-13Nb-13Zr, and Ti-6Al-7Nb is presented as a material for dental implants. The conditions of the plasma electrolytic oxidation process and alkali treatment were designed in this way to enhance the biological properties of the surface of promising Ti alloys. The differences in their surface morphology and, consequently, in the...

Plasma electrolytic oxidation (PEO), as a cost effective and environmentally friendly technology, has been applied on magnesium its alloys to improve wear corrosion resistance. Additionally, combining with particles addition in the electrolyte and/or various post-treatments could diminish intrinsic structural defects of PEO coatings provide multifunctionalities, including resistance, self-lubri...

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...

Abstract. In this work the formation of protective coatings on VT1-0 commercially pure titanium by plasma electrolytic oxidation (PEO) and subsequent fluoropolymer treatment is presented. The structure, morphology, corrosion, mechanical properties formed composite were studied. It was established that PEO are an excellent basis for a solid layer with high adhesion to its surface. presence polyt...
