シチズン独自の表面硬化技術デュラテクト 新技術『DLCブルー』の開発

抄録

  “DURATECT” is Citizen Watch's proprietary surface hardening technology. “DLC-Blue” was developed as a new color for “DURATECT”. “DLC-BLUE” uses diamond-like carbon technology to configure a titanium or stainless steel surface with an adhesion layer, a DLC layer, and a transparent DLC layer, which causes interference of light and achieves a blue color. It has been confirmed that the new “DLC-BLUE” maintains the excellent hardness, scratch resistance, and corrosion resistance of the conventional “DURATECT DLC” while expressing an unprecedented blue color.
