Abstract (en)
[origin: EP2818579A1] A metallic material includes a metal substrate 2 and a modified layer formed on the surface of the metal substrate 2. The modified layer includes three or more protrusions in an area of 10 µm 2 on average protruding from the surface of the metal substrate 2. The protrusions have an average diameter of 1 µm or less when viewed in a direction perpendicular to the surface of the metal substrate. The modified layer may include one or more protrusions in an area of 10 µm 2 on average including a base part protruding from the surface of the metal substrate 2 and a tip part formed on the end of the base part, the protrusions having an average diameter of 1 µm or less when viewed in a direction perpendicular to the surface of the metal substrate 2 and a constricted structure with the outer diameter of the base part being smaller than the outer diameter of the tip part, thereby providing a metallic material having new functions such as hydrophilic properties and luminescence properties.
