摘要: Abstract Plasma electrolytic oxidation (PEO) treatment of Ti6Al4 V (Ti) using various concentrations Na 3 PO4 (NAP) has been carried out. Based on the PEO process, characteristics treated layers, such as structure, chemical composition, phases, roughness, hardness and porosity level were investigated. Irregular micro-channel spots found all surfaces. Larger pores more evident with NAP-7.5 g/L, are considered to be related high intensity micro-arc discharges Ti surface. XRD analyses revealed that surfaces layers composed Ti, TiO 6 anatase. The Profilometry test depicted surface roughness is significantly higher than bare Ti. thickness PEO-treated increased increasing NAP concentration highest sample processed NAP-10 g/L. Among used, 5 g/L showed least porosity. Reflection results portends 10 g/L could serve a potential candidate for clinical purposes.
