        In this research, plasma electrolytic oxidation (PEO) was prepared at duty voltage of 350 and 450 V and processing time of 5 and 10 minutes on Ti-6Al-4V alloy in Na2SiO3 + KOH electrolyte. Then, the adhesion strength and microstructural degradation of the coating surface were investigated through a constant load scratch test, field-emission scanning electron microscope (FE-SEM), and X-ray diffraction (XRD), respectively. The results showed that while increasing the processing time and duty voltage, the density of porosity and the amount of rutile on the coating surface increased. Meanwhile, microstructure degradations like delamination, gross spallation, and buckling spallation decreased due to increased adhesion strength. This resulted from an increase in voltage and processing time. پرونده مقاله
