Abstract
PURPOSE: To prevent lenses from being deformed and slipping from the frames and enhance the decorative properties of the frames by chemically etching the surface of an intermetallic compound having a low Young's modulus.
CONSTITUTION: Part of frames for holding lenses is made of intermetallic compound having a low Young's modulus such as E≤10,000kg/mm2. At this time, the surface of the Ni-Ti intermetallic compound is chemically etched to chemically provide microunevenness. Thus, frames having high decorative properties as well as high corrosion resistance resulting from the intermetallic compound can be obtd.
