Effect of potassium fluoride on the structure and corrosion properties of anodic coatings on Ti6Al4V alloy

Abstract

In this study, KF film was obtained by anodization method on Ti6Al4V material, which is preferred to be used in many areas such as the defense industry, biomedical field and aviation sector. The aim of this study is to compare the corrosion resistance of untreated Ti6Al4V, TiO2 coated Ti6Al4V and KF (potassium fluoride) coated Ti6Al4V samples. 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 highest corrosion resistance was obtained in the new morphological structure obtained by KF coating of the volcano-type structures.
