摘要:
The present invention provides a synergistic composition for making porous bioactive scaffold, bone filler material and non-metallic bioactive coating on metallic implants and a process of coating thereof. A series of bioactive glass composition suitable for application as coating on surgical grade stainless steel, Co-Cr alloy, Titanium and its alloys and the process of application of the coating has been disclosed. The bioactive glass material can also be processed to yield a porous bioactive scaffold and bone filler materials. The bioactive glassy coating material composition comprised of a mixture, based on its oxide content, of silicon di-oxide, Calcium oxide, phosphorous pentoxide, sodium oxide, magnesium oxide, potassium oxide, zinc oxide, boron tri-oxide, and titanium oxide. In accordance with this invention the coating materials are further processed with a mixture of different calcium phosphates including hydroxyl apatites to improve its properties. The coating is bioactive, defect free, highly adherent and suitable for coating surfaces of different load bearing implants for cement less fixation with surrounding hard tissues.
