AB Ti-6Al-4V alloy obtained by powder metallurgy (PM) is a good candidate biomaterial inthe manufacture of dental implants but its inherent porosity makes it have worse corrosion behaviorthan conventionally obtained alloys. In order to improve the corrosion and biological properties,surface modification technologies could be used. The plasma electrolytic oxidation (PEO) processis a novelty process successfully used in case of conventional titanium alloys. The present workinvestigates the e ect of PEO treatment on PM Ti-6Al-4V alloy using two electrolytes. Both coatingsshow good adherence and improved corrosion behavior in artificial saliva, the PEO coatings deliversa steady growth of corrosion resistance from day one until 90 days immersion. Highest corrosionresistance was shown in case of Ca/P enrichment PEO coatings. The cytocompatibility tests indicatedthese coatings seem to be appropriate to improve the bone osseointegration with proper porosity index.
