Hydroxyapatite/tannic acid coating (HA/TA) were prepared on AZ31 magnesium alloys (AZ31) via chemical conversion and biomimetic methods. The characterization and properties of the coating were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), corrosion testing, MC3T3-E1 cell proliferation assay, and MC3T3-E1 cell morphology observation. The results showed that tannic acid as an inducer increased the number of nucleation centers of hydroxyapatite and rendered the morphology more uniform. Compared to bare AZ31 magnesium (Mg) alloys (E corr = −1.462 ± 0.006 V, I corr = (4.8978 ± 0.2455) × 10 −6 A/cm 2 ), the corrosion current density of the HA/TA-coated magnesium alloys ((5.6494 ± 0.3187) × 10 −8 A/cm 2 ) decreased two orders of magnitude, and the corrosion potential of the HA/TA-coated Mg alloys (E corr = −1.304 ± 0.006 V) increased by about 158 mV. This indicated that the HA/TA coating was effectively protecting the AZ31 against corrosion in simulated body fluid (SBF). Cell proliferation assays and cell morphology observations results showed that the HA/TA coating was not toxic to the MC3T3-E1 cells.

“…According to Bakhsheshi-Rad [28], immersion test was performed in SBF for seven days. Specimens (AZ31, TA/AZ31, HA/AZ31, and HA/TA/AZ31) were immersed in a beaker containing 800 mL of SBF, where a funnel was located over the samples to collect evolved hydrogen in a burette (50 mL) placed above the funnel.…”

Abstract:The purpose of this work is to improve the cytocompatibility and corrosion resistance of magnesium alloy in the hope of preparing a biodegradable medical material. The aminated hydroxyethyl cellulose-induced biomimetic hydroxyapatite coating was successfully prepared on AZ31 magnesium alloy surface with a sol-gel spin coating method and biomimetic mineralization. Potentiodynamic polarization tests and electrochemical impedance spectroscopy showed that the hydroxyapatite/aminated hydroxyethyl cellulose (HA/AHEC) coating can greatly improve the corrosion resistance of AZ31 magnesium alloy and reduce the degradation speed in simulated body fluid (SBF). The MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium bromide] method and cell morphology observation results showed that the HA/AHEC coating on AZ31 magnesium alloy has excellent cytocompatibility and biological activity.

replacement implants, magnesium possesses closer elasticity modulus to bones than other metals for effectively avoiding stress shielding effects, which can also avoid the damage and cost associated with secondary surgery. [4,5] However, the major bottleneck inhibiting large-scale clinical utilizations of Mg matrix is the high corrosion rate, which would cause premature loss of mechanical integrity, aggregation of hydrogen, alkalinization of body fluid, and low cytocompatibility, resulting in the implant failure. [6][7][8][9] Coating technology onto Mg-matrix surface is an effective strategy to break the bottleneck. Various coatings, including fluoride coatings, hydroxyapatite coatings, β-tricalcium phosphate coating, and micro-arc oxidation coatings, etc., have been developed to extend the service term of Mg matrix for matching the healing time of bones, and to improve the surface cytocompatibility for accelerating the formation of new bones. [10][11][12] These coatings have greatly improved the corrosion resistance and biocompatibility of Mg matrix. However, in the face of increasing complex clinical requirements of diagnosis, therapy, antibiosis, and anti-inflammatory, it is challenging for the current coatings to achieve effective integration of multiple functionalities, such as the loading/releasing or modification of functional molecules including drugs, antibiotics, contrast agents, and biomacromolecules. [13][14][15] Therefore, the exploration of novel coatings to realize the construction of multifunctional platform is the key to promote the large-scale clinical applications of Mg matrix.Alternatively, ammonium trifluorotitanate (NH 4 TiOF 3 ) is a mesocrystalline intermediate of anatase TiO 2 with favorable cytocompatibility and blood compatibility. [16][17][18][19][20] The conversion degree of NH 4 TiOF 3 to TiO 2 can be regulated to achieve the adjustable crystal structure through changing the temperature and time in solvothermal synthesis. The NH 4 TiOF 3 layer fabricated onto Mg-matrix surface could availably resist the invasion of corrosive media; while its alterable structures correspond to different anticorrosion effects, [20,21] expecting to realize the controllable corrosion of Mg matrix. At present, few researches have been reported on the NH 4 TiOF 3 coatings on Mg-matrix surfaces. Meanwhile, metal-organic frameworks (MOFs), the organic-inorganic hybrid materials with intramolecular pores formed by self-assembly of organic ligands and metal ions or Magnesium (Mg) and its alloys biodegrade safely in human body for implant applications. The major bottleneck inhibiting their clinical utilizations is the high corrosion rate. Modification with anticorrosive and bioactive coatings is an ideal strategy to break the bottleneck. In this study, a multifunctional coating constructed by Zr-based metal-organic framework UiO-66-NH 2 (UiO) and ammonium trifluorotitanate NH 4 TiOF 3 (NTiF) bilayers (UiO/NTiF) is fabricated onto Mg matrix through facile solvothermal method. The inner NTiF layer can be designed ...
