Electrophoretic deposition and characterization of chitosan-hydroxyapatite nanocomposite coatings.

The aim of this research is to create a chitosan/hydroxyapatite composition coating for biomedical applications. The effect was studied of the solution suspension and the pulsed current electrophoretic deposition on the coating composite. The 316L SS. alloys was coated by the pulsed EPD technique with hydroxyapatite in a solution containing 0.15, 0.3, 0.45 and 0.6 mg nano hydroxyapatite in 100 mL of suspension and at constant voltage 30 V. X-ray diffraction spectroscopy (XRD), Scanning electron microscope (SEM), and Fourier transform infrared (FTIR), also the mechanical tests including micro hardness and micro roughness were performed to characterize the deposited coatings.
