Abstract

The aim of this work was preparation, development and characterization of nanostructure bioactive glass (NBG)-titania COATING by sol-gel technique for improvement of biocompatibility of 316L stainless steel implant used in dentistry and orthopaedic surgery. Nano BIOGLASS 58S have been prepared by quick sol-gel method and after calcination at 600oC was added to titania sol in concentrations 30, 50 and 70 grams/liter. Composite sols were coated on STAINLESS STEEL 316L using dip-coating method and heat treated at 600oC. The physicochemical properties, including surface morphology, crystallinity, crystal size and adhesion on steel substrate, of the films were investigated by SEM, EDS, XRD, TEM and micro hardness test method. Macro crack-free and homogeneous BIOGLASS-TiO2 composite COATINGs were obtained, particle size less than 100 nm and an excellent adhesion between the films and the stainless steel substrate (450 vickers). The bioactivity of BIOGLASS-TiO2 composite COATINGs was investigated by immersing the COATINGs in simulated body fluid (SBF) for 30 days. After 30 days immersion, a layer of carbonate-containing apatite was formed on the COATINGs surface. With increasing BIOGLASS concentration the hydroxyl apatite content was increased.
