“…When the precursor concentrations reach a certain level in the case of S4 solution, the H2PO4 -species would be in excess, the diffusion of the ions OH -and PO4 3-from the surface of the electrode into the solution will be preponderant, which would cause a certain solubility of the phosphate based film and more precisely a decrease of the growth of phosphate film 22 .…”

“…The same result was found by Thanh and al. 22 This indicates that a too high concentration of dihydrogen phosphate ions would disadvantage the formation of hydroxide ions OH -, which would lead to the increase of the pH in the vicinity of the cathode 24 . For these reasons, the solution S3 was considered as being the optimal solution.…”

In this work, we have investigated the structural, microstructural, and electrocatalytic properties of hydroxyapatite (HAp) thin films. The HAp films were electrodeposited on stainless-steel (SS) substrates by chronopotentiometry mode from an electrolytic solution. The HAp films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray energy dispersion spectroscopy (EDS). The electrodeposition and electrochemical processes of the hydroxyapatite (HAp) phase were studied by cyclic voltammetry. This HAp/SS system acting as an anode was used for the first time to electrodegrade Rhodamine B (RhB) in aqueous solutions. To follow the degradation kinetics, we used UV-visible spectroscopy. Several parameters such as the current density and the initial concentration of electrolytic solution were determined to optimize the electrodegradation of RhB. The decrease of RhB concentration followed pseudo-first order kinetics law. The rate of RhB degradation in presence of HAp/SS electrode can reach interesting high performance, depending on the electrocatalysis experimental conditions.

“…7,8 Nevertheless, the literature confirms that these problems can be mitigated by depositing hydroxyapatite (HAP) coatings on metallic implants. [9][10][11][12][13][14][15][16][17] Hydroxyapatite (HAP) holds a significant position as an inorganic biomaterial, but bulk HAP ceramics possess poor mechanical properties restricting its use for non-load-bearing implant applications. To overcome this limitation, HAP is being coated on metals and their alloys to derive the advantages of both the bioactivity of HAP and the mechanical performance of metals.…”

In this research, the laser rapid manufacturing (LRM) additive manufacturing process was used to deposit multifunctional hydroxyapatite (HAP) coatings on high nitrogen stainless steel. LRM overcomes the limitations of conventional coating processes by producing coatings with metallurgical bond, osseointegration, and infection inhibition properties. The microstructure, microhardness, antibacterial efficacy, and bioactivity of the coatings were investigated. The microstructure studies established that the coatings consist of austenite dendrites with HAP and some reaction products primarily occurring in the inter-dendritic regions. A Vickers microhardness test confirmed the hardness values of deposited HAP coatings to be higher than those of the bare 254SS samples, while a fluorescence activated cell sorting test confirmed their superior antibacterial properties as compared with pristine samples. The coated samples immersed in simulated body fluid showed rapid apatite forming ability. The results obtained in this research signify the potential application of the LRM process in synthesizing multifunctional orthopaedic coatings.

Calcium phosphate (Ca‐P) ceramics are used in orthopedics and dentistry due to their excellent biocompatibility and osseointegration. In this study, calcium phosphate coatings were deposited on Nitinol shape memory alloy by a pulse electrodeposition technique. Prior to the deposition, a thermochemical treatment was used on the alloy to improve corrosion resistance and also to reduce the Ni ions release from the alloy. The morphology, structure, and composition of the coatings were investigated by X‐ray diffraction analysis (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The result of Ni release test showed that hydroxyapatite (HA) coating has the lowest amount of the released Ni in Ringer's solution. The results of cell culture test revealed that the cells propagation and growth condition on HA‐coated sample is better than bare and Ca‐P‐coated substrates. The corrosion behavior was examined in simulated body fluid (SBF) using Tafel polarization and electrochemical impedance spectroscopy (EIS) tests, which showed that HA‐coated sample exhibited larger corrosion resistance in simulated body fluid. Results indicate that the stability of hydroxyapatite phase and the special morphology of HA coating are responsible for the better biological behavior of this coating.
