微細構造形成によるステンレス鋼へのレーザ加飾システム

抄録

The purpose of this study is to develop a decorative laser marking system on stainless steel. In the conventional research, since the thickness of the oxide film is controlled in order to reflect the interference color, there is a problem that the number of colors is small and it is difficult to use it for decorative purposes. Therefore, we propose a method to reflect various colors by forming a microstructure consisting of two types of oxide films. The proposed method demonstrated the improvement of color resolution due to the effect of simultaneous color mixing, and developed a system that can mark stainless steel blades.
