METHOD OF SURFACE TREATMENT FOR METALLIC GLASS PART, AND METALLIC GLASS PART WITH ITS SURFACE TREATED BY THE METHOD

摘要

There is provided a metallic glass component with its surface layer having both durability of a film and chromatic color properties, and a method for forming the surface layer. Surface active treatment is performed wherein the surface of the metallic glass component 10 is reacted with a mixed aqueous solution of nitric acid and hydrofluoric acid 18 to remove an oxide film 12 and to provide an anchor bond shape 14 on the surface of a metallic glass component 10, and electroplating or electroless plating is then performed, to form a plating film 16 on the surface of the metallic glass component 10. It is thereby possible to form a surface layer of a metallic glass which has both durability and a chromatic color.
