Influence of NaF film produced by plasma electrolytic oxidation method on corrosion resistance of Cp-Ti

Abstract

– In this study, sodium fluoride (NaF) thin film was obtained by the plasma electrolytic oxidation (PEO) method on commercially pure titanium (Cp-Ti) material, which is frequently used in the biomedical field. The aim of this study is to compare the corrosion resistance of the samples with untreated Cp-Ti and coated with NaF. XRD and SEM were used for the structural characterization of the samples. Corrosion experiments were performed in simulated body fluid (SBF). According to the results, the thin film obtained from the NaF coated sample exhibited higher resistance to corrosion.
