Dip Coated Magnesium-Substituted Hydroxyapatite Coatings on Magnesium Alloy for Biomedical Applications

Abstract

Magnesium-substituted hydroxyapatite coatings have been deposited on magnesium alloy for biomedical applications by sol–gel technology. The Ca(10−x)Mgx(PO4)6(OH)2 coatings obtained, with magnesium contents up to x = 1.5, show dense and compact and with visible cracks. The results of Hydrogen (H2) evolution testing in Hank’s solution show that magnesium-substituted hydroxyapatite coatings can improve the corrosion resistance of magnesium alloy.

Halloysite Nanotube-Reinforced Ion-Incorporated Hydroxyapatite-Chitosan Composite Coating on Ti-6Al-4 V Alloy for Implant Application

“…e improved cell viability of the HNT-CS-MHA composite coating is mainly owing to the substitution of minerals such as Mg 2+ in HA and also Zn 2+ incorporation in HNTs present in the HNT-CS-MHA composite coating [47,48]. e cell viability of the HNT-CS-MHA composite coating is shown to enhance on increasing the days from 1 to 7 days of MG63 cell culture medium which indicates the nontoxic nature of this composite coating.…”
