BIOGLASS AND GLASS CERAMIC COMPOSITE COATINGS ON METALLIC ALLOYS

摘要

A new composite-artificial bone which can combine with human bone by chemical bond is presented in this paper. This composite comprises a coating and an alloy (titanium alloy, stianless steel or cobalt-chrome-molybdenum). The coating is made by the mixture of bioactive glass and glass ceramic. The coating is sintered on the surface of the alloy,between the coating and alloy there is a layer of transition. Composite artificial bone has a good strength and activity and since 1988, it has been used on clinic in a large number.
