The effect of applied current density on the surface morphology of deposited calcium phosphate coatings on titanium

► Electrochemically deposited brushite coatings as precursors for HA formation. ► Brushite coating with small crystallite domain size of 15.6 nm was deposited. ► The applied current density determines the porosity of brushite coatings. ► The crystallite domain size of HA is controlled by porosity of brushite coatings.
