What is it about?

Hydroxyapatite-chitosan (HAp-CS) was coated with 2205 duplex stainless steel (DSS) by utilizing electrophoretic deposition (EPD) technique, enhancing the resistance to corrosion onto DSS. In this study, the corrosion resistance of uncoated and coated samples were evaluated in Ringer's physiological solution by various electrochemical studies. The surface morphology of coatings and porosity were investigated by field emission, scanning electron microscopy (FESEM) test and Image J 1.42q software, respectively. The optimum result for successful coating of DSS was acquired with a coating under condition 30 V for three minutes, were the corrosion's current density (Icoor) at (4.32 μA cm−2).

Why is it important?

The objective of this research is to study the effects of HAp-CS coating on the DSS by EPD to improve their biocompatibility and resistance to corrosion.


The nanocomposite Hydroxyapatite-chitosan (HAp-CS) were successfully deposited on the surface of 2205 DSS with homogenous and less porous structure.
