Microscale Incorporation of Elemental Cu from the Roller during Splat Cooling of Amorphous Metal Ribbon
PdZrNi and FePBCr amorphous metallic foils were prepared by roller quenching, and the incorporation of elemental Cu from the Cu roller into the contact surface of the metallic foil was investigated by X-ray photoelectron spectroscopy. It was found that Cu was incorporated into the surface of both metallic foils. This result suggests that the catalytic activity of the metallic alloy can be attributed to elemental Cu. This phenomenon can be used to modify the surface of an amorphous alloy to change its surface properties.
