Abstract

Fluoridated hydroxyapatite (FHAp) coatings were deposited on 316L stainless steel substrates using an electrochemical technique. Different concentrations of F ions were incorporated into the apatite structure by adding NaF into the electrolyte. The coatings were uniform and dense, with a thickness from 6.07 to 9.58 pm when the F‘ concentration increased from 0 to 0.003 M. Analysis of TR, EDX, X-ray and SEM characterizations showed that F' ions doped on HAp with volume percentage of 1.7 % when the concentration of F'added to 0.002 M, FHAp coating has structure of rod-shaped crystals with size of about 100 run and characteristics of the FHAp molecule structure.
