Focusing on DLC films containing manganese (Mn), which promotes bone formation, we investigated the structural changes associated with Mn elution. Using positron annihilation spectroscopy (PAS) with a low-energy positron beam, we determined that the size of vacancy-type defects within the DLC film increases. Furthermore, by performing K-edge X-ray absorption spectroscopy (XAS) measurements on Mn using synchrotron radiation, we clarified that the Mn within the Mn-DLC film is metallically bound. It is believed that Mn forms metallic nanoparticles within the DLC film.
