The aim of this work was to evaluate the corrosion behavior of the uncoated and coated titanium (Ti) and study the effect of calcium phosphate (CaP) on corrosion behavior of hydroxyapatite (HA) coatings in simulated body fluid (Ringer’s solution). Three types of coatings: HA, HA + 10 wt% CaP, and HA + 20 wt% CaP on titanium were made using plasma-spraying technique. Structural characterization techniques including X-ray diffraction and scanning electron microscopy/energy dispersive X-ray spectroscopy were used to investigate the crystallinity, microstructure and morphology and of the coatings. Electrochemical potentiodynamic test were performed to determine the corrosion resistance of uncoated and all three coatings in Ringer’s solution. The corrosion resistance of plasma sprayed HA coating on titanium was found maximum.
