Synthesis of Strontium Substituted Hydroxyapatite Coating on Titanium Via Hydrothermal Method
Main Article Content
Abstract
In this work, Strontium substituted hydroxyapatite (SrHA) coatings were successfully deposited onto etched titanium substrates in solutions of H2SO4 and HCl. The deposition was achieved by hydrothermal method by immersing the substrates in a solution containing Ca(NO3)2.4H2O, NH4H2PO4, and 5% Sr(NO3)2, followed by heating at 200°C for 12 hours. X-ray diffraction (XRD) analysis confirmed that all SrHA coatings exhibited a crystalline hydroxyapatite structure. Field-emission scanning electron microscopy (FE-SEM) revealed that the SrHA coatings exhibited microstructure. The reults of testing Bioactivity and in vitro biocompatibility of the SrHA-coated titanium substrates using SBF solution and baby hamster kidney (BHK) cells showed good biological properties of the SrHA coatings.
