| Outline of Final Research Achievements |
The main purpose of this research is to clarify the mechanism of laser coloring and to develop a new technology of metallic coloring. The principle is to use laser irradiation to generate a thin oxide film on the target surface, and color can be observed due to the light interference phenomena. In this research, a new oxide film generation device was developed. The affection of the laser irradiation parameter to the oxide film generation and the observed color was clarified. By carefully control the thickness and surface profile of the oxide film, precision coloring with multiple colors are realized on different kinds of metallic materials.
