Fabrication of Bioactive Stainless Steel by the Function of Apatite Nuclei

Abstract:

Micropores were formed on the surfaces of stainless steel (SUS) by sandblasting methods and Apatite Nuclei (AN) were formed in the pores. By this treatments, a bioactive SUS was fabricated. Apatite-forming ability of the SUS was evaluated by immersing in an acellular simulated body fluid. Formation of bonelike apatite was induced on the surface of the SUS within 1 day. High bonding strength of the bonelike apatite layer was achieved by a mechanical interlocking effect between the bonelike apatite formed in the pores and the SUS specimen.
