Preparation and characterization of hydroxyapatite/titania composite coating on NiTi alloy by electrochemical deposition

Optimized Electrodeposition Concentrations for Hydroxyapatite Coatings on CoCrMo biomedical alloys by computational techniques

“…According to EIS analyze results, the samples which phase angle closer to 90 C, indicate better capacitive effects and higher Z values at low frequency regions. It is known that as the higher Z at low frequency range indicates a higher corrosion resistance in simulated body fluid (SBF) [24]. On that account, phase angle determinations from EIS analysis were focused on corrosion performance of the alloys.…”

“…It is known that Ca/P ratio in hydroxyapatite molecule is 1.6. Many researchers use electrolyte concentrations with a ratio of Ca/P: 1.6 to provide hydroxyapatite formation [9,[21][22][23][24][25]. For synthesis of an ideal hydroxyapatite molecule, it is clear that Ca +2 affect the coating more than P À ions in solution.…”

Fabrication and Properties of Micro- and Nanostructured Coatings Using Electrochemical Depositions

“…These factors, especially the electrical current density in the unit surface of the cathode, determine the deposition rate. The electrical current distribution in lumps of cathodic surfaces are more than recesses, and this change in current density affects metal distribution, as the thickness of coating deposition corresponds with the current density (22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33).…”

“…Chemical deposition techniques are utilized to synthesize composite coatings since they offer coatings with even thickness. The DTD 943 standard explains deposition of composite Co-CrC coatings (15,26,27,49,56,61,73,100,106,115,128,(151)(152)(153)(154)(155)(156)(157) ELD coating had relatively flat and smooth surfaces, composed of strip-like crystals with a length and width of 5-7 mm and 1 mm, respectively. Once ELD coating was resoaked in MSBF for several days, the newly developed EBG coating was a denser, thicker, and more favorably crystallized HA-COL composite coating.…”

The Effect of Using Different Types of HA on Compressive Strength of HA/MWCNTs-OH/BSA Composite for Use as Bone Replacement Materials

“…HA is nontoxic, biocompatible and bioactive component where it can support growth of osteoblasts on surface of bone replacement materials. However, application of HA based bone replacement materials is limited to the low-stress region due to its relatively low mechanical properties [10,11]. Nowadays, many researches are carried out to improve the mechanical properties of HA based composite without neglecting its bioactive performance.…”
