The bonding of Bioglass to a cobalt-chromium surgical implant alloy.

A biocompatible composite implant system was developed by coating Bioglass onto cobalt-chromium alloy substrates. Strong bonding between glass and metal was obtained by immersion of preoxidized implants into molten Bioglass under controlled conditions. The thin, adherent Bioglass coating provides the capability of bonding directly to bone, while the underlying metal substrate gives the composite implants sufficient strength to be used in load bearing applications.
