Effect of electrodeposition modes on surface characteristics and corrosion properties of fluorine-doped hydroxyapatite coatings on Mg–Zn–Ca alloy

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

“…Upon investigating, we can see that a significant increase in phase angle with increase of phosphate concentration, especially above 0.02 M. It is suggested that after a critical value of phosphate molarities, hydroxyapatite formation increases significantly, resulting effect of H 2 O 2 concentration more important. It is reported in recent studies positive effect of H 2 O 2 on the homogenous hydroxyapatite formation [7,9,25,26]. On the contrary, increases in H 2 O 2 concentration did now show a considerable effect in phase angle.…”

Sustainable application of magnesium alloy through Electrodeposition of Hydroxyapatite Coating

“…A strong ν3 PO 4 3-vibration band, associated with the internalmodes of PO 4 3-(P-O asymmetric stretching vibrations), are observed inside the frequency range fromca. 1000 cm -1 to 1100 cm -1 at 1009 cm -1 and 1088 cm -1…”

“…The peaks at 1459, 1409 and 1337 cm -1 are due to the presence of carbonate ions in the hydroxyapatite structure. It is well known that carbonate, generated from reaction ofatmospheric CO2 with aqueous solutions, readily substitutes for phosphate ions (B-type incorporation;i.e., CO 3 2-for PO 4 3-substitutions) in the crystal structure of hydroxyapatite. The introduction ofthese different ions was beneficial to the biocompatibility because of natural bone tissue also containedMg 2+ , Na + , HPO 4 2-and CO 3 2-which gives an additional advantage because it leads to an enhancedosseointegration.…”

The role of titania on the microstructure, biocorrosion and mechanical properties of Mg/HA-based nanocomposites for potential application in bone repair

“…Alloying Mg with safe elements such as Ca [19], Zn [20] and Zr [21] is one of them. Second, modification the surface of conventional Mg alloys via bioactive coatings including hydroxyapatite (HA, Ca 10 (PO 4 ) 6 (OH) 2 ) [22][23][24], Si [25,26], calcium-phosphorus [27], TiO 2 [28], bonelike apatite [29] and brushite [6]. Fabrication Mgmatrix composite (MMC) reinforced with bioactive ceramics [30] is another route to reduce degradation rate of Mg-based alloys.…”
