“…The Young`s modulus is a crucial parameter, as it ensures a strong connection between the implant and the bone [3]. The materials to bone regeneration should have a value of Young`s modulus similar or lower that of a natural human bone (15)(16)(17)(18)(19)(20) [12,13]. Poor mechanical properties caused the fast dissolution of the coatings in a physiological environment [31].…”

“…There are some reports on possible adverse e effects of both alloying elements of the Ti6Al4V: vanadium may provoke cytological responses and neurogenic disorders, and aluminum softens bone, do damage to nerve cells and disturbance of the function of enzymes [7][8][9][10]. The titanium alloy Ti13Zr13Nb possesses no harmful elements (aluminum and vanadium), is characterized by relatively low Young modulus (~ 80 GPa ) [8] compared to Ti6Al4V (~110 GPa) [11] and is more mechanically compatible with the bone (15)(16)(17)(18)(19)(20) [12,13].…”

“…nanooxidation [8], laser treatment [14] or hydroxyapatite deposition [15]. Many deposition methods of hydroxyapatite/ nanohydroxyapatite were so far investigated, such as electrophoretic deposition (EPD) [16], plasma spraying [17], sol-gel methods [18] and biomimetic deposition [7].…”

“…The main advantage of EPD is to produce porous coatings for enhancement of the bone growth into the porous structure of the coating. To prevent the shrinkage of ceramic nanohydroxyapatite coating after EPD, the sample should to sintered at the vacuum atmosphere at 800-1200º C [15]. The post-surgery treatment after implantation is carried out by an administration of antibiotics.…”

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.

“…There are many impact parameters, such as voltage, time, pH value, and solvent medium that influence coating characteristics [19]- [25]. Several researches had been using the wide range of deposition voltage, which is approximately 2V -500V for different deposition time that is 3 seconds until 90 minutes.…”

An α+β type titanium alloy, Ti-6Al-4V, has been coated with hydroxyapatite through electrophoretic deposition (EPD) method to improve quality of the alloy surface, in order to fulfill bioactivity requirement for orthodontic application as dental roots. The deposition process was conducted by EPD at different voltages (2 volts, 5 volts, and 10 volts) and time (2 minutes and 5 minutes). After deposition, the material was heated at temperature 700 o C for 1 hour using a vacuum furnace. Coated samples analysis was conducted by scanning electron microscope (SEM) and energy dispersive X-ray (EDX) to examine coating layer morphology and its chemical composition, respectively. Experimental results showed that the voltage and time deposition gives different effects to surface coverage and thickness of hydroxyapatite layers. Optimum layer for dental roots is obtained from the voltage of 5 volts for 5 minutes with 100% surface coverage value and 45.55μm in thickness. With low voltage and short deposition time for making a uniform coating layer, this process is much cheaper than other processes, and it is predicted to be favorable for improving osseointegration of dental roots.
