چكيده فارسي :
Nanocomposite ceramic coatings were fabricated on Ti6Al4V titanium alloy via plasma electrolytic oxidation (PEO) method in electrolytes containing different concentrations of aluminate and phosphate. Morphology and chemical composition of the coatings were evaluated by field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD). Electrochemical corrosion behavior of the coatings was determined by potentiodynamic polarization test in phosphate buffered saline (PBS) solution. The results showed that the sample coated in mixed aluminate/phosphate electrolyte with 10 g/L concentration of each of the compounds had the best corrosion resistance.
