چکیده
In order to increase the corrosion resistance and improve the biocompatibility of Ti-6Al-4V alloy used in medical applications such as implants, it has been modified with various methods including PEO. On the other hand, this alloy is also capable of heat treatment. In this study, firstly different structures were obtained by heat treatment of Ti-6Al-4V substrate and then different structures were coated with the same parameters, by PEO method. The scanning electron microscope equipped with EDS was used to investigate the morphology and cross-sectional of the coatings. X-ray diffraction was also applied to analyze the phases created in the coating. Additionally, investigation of surface topography was performed by atomic force microscopy. Results have represented that the martensitic structure has a lower porosity with more regular dispersion. The creation of coating with martensitic structure also shows good thickness with high quality smoothness. On the other hand, the coating of the α-plate and inter-grain β structure were included large and irregular porosities.کلیدواژه ها
