Ti6Al4V Alaşımına Sol-Jel Yöntemi ile Yapılan Hidroksiapatit Kaplamalarda Dietanolaminin Kaplama Morfolojisine ve Korozyon Dayanımına Etkisi


Titanium and its alloys are preferred in biomaterial applications due to their mechanical strength and biotolerant structure. However, if they are corroded in the human body, they can cause the release of harmful ions. Hydroxyapatite is a ceramic and bioactive material, and it is also used as a coating layer for increasing the corrosion resistance of biomaterials. In this study, hydroxyapatite coatings were made using the sol-gel method to improve the corrosion resistance of Ti6Al4V alloy. By adding different ratios of diethanolamine (DEA, C4H11NO2) to the prepared hydroxyapatite solutions, cracked structures that are likely to occur in the sol-gel process has been checked and tried to be reduced. It has been aimed to observe the changes in the overall morphology and corrosion resistance of the coatings. Samples were analyzed using scanning electron microscopy (SEM-EDS) and X-Ray diffraction (XRD). Electrochemical-potentiodynamic corrosion tests were carried out in the prepared simulated body fluid. As a result of the study, it was observed that the cracked structures and the coating thickness increased in morphology with the increase in the DEA contribution rate. It was seen that the addition of DEA increases the corrosion resistance, but the increase in the amount of DEA negatively affects the corrosion resistance.
