Abstract

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 is reacted with a mixed aqueous solution of nitric acid and hydrofluoric acid to remove an oxide film and to provide an anchor bond shape on the surface of a metallic glass component, and electroplating or electroless plating is then performed, to form a plating film on the surface of the metallic glass component. It is thereby possible to form a surface layer of a metallic glass which has both durability and a chromatic color.
