In recent years, surgical operations of artificial joint replacement have been gradually increased for high quality of life, and the shortening fixing period of joint components to bone is strongly requested. Then, giving high osteoconductivity has been artificially given to the joint components surface for promoting the fixation. In this study, the possibility to give an osteoconductivity on titanium surface by EDM is fundamentally discussed. While soaking the EDMed sample in the simulated body fluid for the purpose of the apatite formation ability, the formation of white deposits unlike hydroxyapatite was confirmed on the sample. In this report, the composition of the white deposits was investigated by XRD and Raman spectroscopy. Furthermore, the formation mechanism were experimentally discussed.
