ABSTRACT
Micrometer-sized pores were formed on the surface of cobalt-chromium (Co-Cr) alloys by sandblasting method. In order to provide bioactivity to the Co-Cr alloys, the alloys were soaked in SBF and heated. By this treatment, amorphous calcium phosphate film was formed on the Co-Cr alloys. Apatite-forming ability of the specimens was evaluated by using SBF.
