Bioactive Glass-Ceramic Coating Of Titanium Substrates By Alkaline Hydrothermal Process, Mohamed Gebril

Electronic Thesis and Dissertation Repository

Surface modification is a well-known approach to enhance the osseointegration of titanium dental implants. In this study, a novel hydrothermal method for coating titanium surfaces with bioactive glass was developed. Our method included sol-gel synthesis of bioactive glass, followed by hydrothermal coating of titanium under different NaOH concentrations. The surface properties of coated substrates were evaluated by scanning electron microscopy, X-ray diffraction, energy dispersive X-ray spectroscopy, and surface profilometry. By varying the alkalinity of the hydrothermal process, different surface topographies, crystalline phases and chemistries could be obtained. Soaking the hydrothermally coated titanium substrates in simulated body fluid resulted in hydroxyapatite …
