Abstract

Sol-gel derived organically modified silicates containing calcium ions showed the ability to form hydroxyapatite (HA) in a simulated body fluid (SBF). Using the sol-gel method, we prepared a double layered coating on a-titanium (Ti) and Stainless steel 304 (SUS) plates. The double layered coating consisted of a methyltriethoxysilane (MTES) derived organic silicate layer, with a MTES-Ca-Nb-Ta layer on top which, prepared from MTES, calcium nitrate tetrahydrate, pentaethoxy-niobium and pentaethoxy-tantalum. The MTES coatings on the Ti and SUS had adhesive strengths at 5.2 and 4.6 MPa, respectively. HA formed on the surfaces of the double layered coatings on the Ti substrates after immersion in SBF at 3 days.
