| Outline of Final Research Achievements |
As fundamental experimental analysis for atmospheric pressure plasma irradiation application in the dental field, the surface free energy of the irradiated surface in the atmospheric pressure plasma irradiation on the metal was measured. As a result, the increase of the surface free energy on metal surface due to a hydrogen bonding force and a dipole force were shown. Shifts to the higher binding energy side in each containing element indicating were shown by X - ray photoelectron spectroscopy (XPS), and high reactivity towards the oxidation state were interpreted. A broad peak in low 2θ degree range was detected by XRD analysis. The increase of noncrystalline components in the surface layer of alloys with irradiation was therefore shown. In addition, an increase in the surface free energies of the orthodontic resin bonding materials as a polymer compound,was shown.
