TL;DR
This study examines how different electrode systems affect the properties of calcium phosphate coatings deposited on a titanium alloy, finding that they influence morphology and corrosion resistance.
Contribution
The novelty lies in investigating the impact of two- and three-electrode systems on the electrodeposition of CaP coatings, a previously unstudied aspect.
Findings
Both two- and three-electrode systems effectively deposit CaP coatings with varying morphologies.
Hydroxyapatite is the primary compound in the coatings, with dicalcium phosphate dihydrate appearing under more cathodic conditions.
Optimal coatings for biomedical use were achieved at specific voltages in both electrode systems.
Abstract
The morphology and physicochemical properties of electrochemically deposited CaP coatings depend on the applied process parameters; however, the influence of different electrode systems has not been studied so far. In this work, the possibility of electrochemical deposition of CaP coatings on Ti6Al7Nb alloy using different electrode systems (two-electrode and three-electrode) and the influence of the electrode system and selected ranges of deposition parameters on the properties of the deposited CaP coatings were investigated. The morphology and physicochemical properties of the CaP coatings were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), Raman spectroscopy, X-ray diffraction (XRD), and corrosion studies. The results confirmed the effective electrodeposition of CaP coatings using both electrode systems. The applied electrode system…
