Abstract

Auger spectroscopy and ion beam milling were used to determine surface compositional profiles on a series of bioglass implant materials after exposure to simulated body conditions. Four glasses were examined, a soda‐lime‐silica glass and 3 compositions produced by adding 3, 6, and 12 wt% P2O5 to the ternary glass. An SiO2‐rich layer is formed on the surface of all glasses investigated. As P2O5 is added to the bulk composition, a second film rich in Ca and P forms at the SiO2‐rich film‐water interface. The rate of formation of the Ca‐P film increases as the P2O5 content of the bulk glass increases. When glasses are corroded under identical conditions, the thickness of the Ca‐P layer increases as the P2O5 content of the bulk composition is increased.
