N2 - In this work, protective hydroxyapatite (HA) films were deposited on AISI 316L stainless steel using a controlled chemical precipitation process (CCP). The crystallization characteristics of each film at different temperatures (300, 600 and 800°C) and its effect on the electrochemical performance were analyzed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and Electrochemical impedance spectroscopy (EIS). The results indicate that during the synthesis, good protective coatings were obtained even though some traces of CaHPO4.H2O were detected. The electrochemical properties (higher charge transfer resistance) are towards correlated with the crystallinity and particle size forming the film. Hence, the HA coating sintered at 800°C showed greater protection in chlorine media compared to lower sintering temperatures and uncoated material.
