ABSTRACT:
A method metallurgically bonds a thin film of easily amorphized material on a metallic substrate having a large thermal conductivity, and then irradiates all or selected portions of the thin film with a pulse laser. The irradiated portions become amorphous by rapidly heating and cooling. Therefore, a whole surface which is an amorphous layer or a part of a surface which is an amorphous layer is obtained. In the latter, a porous amorphous metal layer is obtained by subsequent acid elution and by removing the non-amorphous part.
