TiO_2 is one of the photo catalyst materials that are focused due to superior property such as anti-bacterium characteristic. It is an extremely stable material that doesn't dissolve to an alkali, water, and an organic solvent in the normal temperature and the normal pressure, and doesn't react with the gas with a strong reactiveness such as the hydrogen fluoride, chlorines, and hydrogen sulfides. Moreover, it excels as a photo catalyst in durability, and it has a lot of advantages in the economy, stability, and the practicality, etc... There are two kinds of TiO_2 industrially used from the difference of the crystal structure, the Anatase type and the Rutile type. Generally the Anatase type is used from the viewpoint of the photo catalyst revitalization. In this study, the adhesive strength of TiO_2 coating processed by the Sol-Gel method was evaluated by using the scratch test with observation and analysis of scratched surface. After that, influence of the thermal treatment temperature and the dipping procedure on the adhesive strength was discussed.
