“…On the other hand, the corrosion rate is still at a minimal level. The investigationsof nanoHAp/nanoAg coatings were already performed, but for thick coatings or coatingson TiO 2 layers [24,30]. The mechanical properties of both types of coating differ slightly.…”

The aim of this research was to study the properties of nanohydroxyapatite (nanoHAp) and nanohydroxyapatite, doped with nanosilver (nanoHAp/nanoAg), coatings obtained by an electrophoretic deposition process. The suspensions was prepared by dispersing 0.1 g of HAp nanopowder for nanoHAp coatings and 0.1 g of nanoHAp and 0.025 g nanoAg for nanoHAp/nanoAg coatings. The deposition was carried out for 1 min at 50 V voltage followed by drying at room temperature for 24 h and heating at 800°C for 1 h in vacuum. The thickness of the nanoHAp and nanoHAp/nanoAg coatings was found as of about 5 µm. The corrosion behavior tests made by potentiodynamic methods brought out slightly higher values of corrosion current for nanoHAp coatings and nanoHAp/nanoAg coatings as compared to the reference Ti13Zr13Nb specimen. The nanohardness of the nanoHAp coatings achieved 0.020 ± 0.004 GPa and of the nanoHAp/nanoAg coatings 0.026 ± 0.012 GPa. Nanoscratch test of the nanoHAp and nanoHAp/nanoAg coatings revealed an increased Critical Friction (mN) in the presence of nanosilver particles. The wettability angles decreased for nanoHAp/nanoAg coatings comparing to pure nanoHAp coatings on titanium alloy.

“…In this sense, electrolytic deposition (ED) has proven to be among the most versatile methods for the synthesis of ion-substituted HAP composite coatings [15,16], with characteristics superior to conventional deposition techniques (low process temperature, low-cost equipment, probability of fabricating onto porous substrates of complicated shapes, and simple control of coating properties). There are several reports on the individual substitution of several ions such as Sr, Mg, Mn, Ag, Zn, Na, and F into HAP coating [17][18][19][20][21][22][23]; however, to the best of our knowledge, there are very limited reports concerning the electrodeposition of Cu 2? -substituted HAP coating on metallic substrate.…”

This work elucidated the antibacterial efficacy, corrosion resistance, and cytotoxicity of electroplated copper-substituted hydroxyapatite (CuHAP) coating on titanium (Ti). The fabricated CuHAP coatings were characterized by scanning electron microscopy, energydispersive X-ray analysis spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction studies. The CuHAP coating had needle-like apatite crystals, the doping of Cu 2? into HAP reduced porosity, and the coating became denser. The CuHAP crystals were carbonated with a few of Cu 2? incorporation (about 0.80 wt%). The Cu 2? ions were homogenously deposited into HAP films. Potentiodynamic polarisation test revealed that the CuHAP coating provided good barrier characteristics and achieved superior corrosion protection for Ti substrates. The in vitro antibacterial activity of asprepared CuHAP coating was evaluated against Escherichia coli and was found to be effectively high against bacterial colonization. Bioactivity test conducted by soaking the coatings in simulated body fluid demonstrated that CuHAP coating can quickly induce bone-like apatite nucleation and growth. In vitro biocompatibility tests, MTT, were employed to assess the cytotoxicity of Cu-HAP coating with osteoblast-like MC3T3-E1 cells. The obtained HAP coating doped with a low content of Cu 2? exhibited good cytocompatibility and had no toxicity toward MC3T3-E1.

“…For instance, successful results have been shown recently for silver-incorporated HA coatings developed by plasma electrolytic oxidation process on Ti6Al4V substrates [92]. Significant antibacterial properties and considerable biocompatibility as well as low toxicity of the Ag-HA thin films electrochemically deposited on TiO 2 nanotubes were shown elsewhere [93]. Similar results have been reported for silver-containing HA coating synthesized by sol-gel method [94], plasma spraying [95], and ion beam-assisted deposition [96,97].…”
