Abstract

A new series of bioactive glasses have been prepared with thermal expansion coefficients that more closely match that of Ti-based implant alloys. It is proposed that these glasses be used as coatings on biological implants that would provide improved fixation between the implant and tissue. As glasses are subject to environmentally assisted crack growth, it is important to develop an understanding of the stress corrosion crack growth (SCCG) behavior of this new family of glasses; furthermore, it is equally important to determine the effect of bioactivity on the SCCG properties of these glasses. This report will present the progress to date in the study of the SCCG properties of these new bioactive glasses
