“…The bioactive HAP coating on metallic materials is proven to be efficient for better biocompatibility, bone bonding ability and osteointegrity [5][6][7][8][9][10][11]. Enormous numbers of papers have been reported on the different coating methods of HAP on metallic substrates which include plasma spraying [12], pulsed laser deposition [13], ion implantation [14], sputtering [15], sol-gel [16], biomimetic [17] and electrodeposition method [18][19][20][21][22]. Plasma spray is one of the commercial methods for depositing HAP coatings on titanium-base and other metal-base implants, but the extremely high temperature used in plasma spray process may lead to decomposition of HAP.…”

“…Different coating technologies like biomimetic, pulsed laser deposition, electrochemical deposition, plasma spraying, electrophoretic, micro-arc method, etc. [15][16][17][18][19][20] have been adopted for the development of Si-␤-TCP coating on the implant. Among the several coating methods, electrophoretic deposition (EPD) operates with mild conditions and forms crystalline deposits with low residual stresses and thus it becomes a promising method for preparing coatings on surgical grade implants [21].…”

Asian Ceram. Soc. (2015), http://dx. a b s t r a c tWe have developed a novel approach to introduce silica-doped ␤-tricalcium phosphate (Si-␤-TCP) on 316L SS substrates for enhanced biological properties. Doping of ␤-TCP with silica loadings ranging from 0 to 8 mol% was carried out using chemical precipitation method. Si-␤-TCP powder was sintered at 800 • C followed by coating it on 316L SS substrate using electrophoretic deposition. The coated and uncoated samples were investigated by various characterization techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM) and X-ray fluorescence spectroscopy (XRF). Biomineralization ability of the coatings was evaluated by immersing in simulated body fluid (SBF) solution for different number of days such as 7, 14, 21 and 28 days. The results obtained in our study have shown that the apatite formation ability was high for the 8 mol% of Si-␤-TCP. This will promote better biomineralization ability compared to the other coatings.

“…Sol-gel technique is generally preferred to coat ceramic materials because it does not require high temperature treatment and is an easy and costeffective process ( Ref 21). Several attempts have already been made to develop ceramic coating over 316L SS to improve its corrosion resistance and biocompatibility (Ref [22][23][24].…”

The effect of Si:Zr ratio on the in vitro bioactivity and electrochemical corrosion behavior of SiO 2 :ZrO 2 -mixed oxide-coated 316L stainless steel (SS) was evaluated in simulated body fluid (SBF) solution for 72, 120, and 168 h. Growth of Hydroxyapatite (HAp) was accelerated when Si content in the coating was increased. The Zr content in the coating improved the corrosion resistance of 316L SS rather than accelerating the HAp growth. When the Si:Zr ratio was 50:50, the coating exhibited significant improvement in corrosion resistance as well as HAp growth. The mechanism of HAp growth was proposed based on the change in surface zeta potential values of the coatings. Potentiodynamic polarization studies revealed about 10 and 5 times reduction in corrosion current density (i corr ) values for SiO 2 :ZrO 2 (50:50)-coated 316L SS after 168 h of immersion compared to SiO 2 , ZrO 2 , and Si:Zr (70:30) coatings in SBF solutions thus confirming the superior corrosion resistance. The equivalent circuit parameters derived from electrochemical impedance spectroscopy studies further confirmed significant improvement in charge transfer resistance value even after 168 h of exposure.
