ABSTRACT:
A workpiece is processed by abrading a surface of its amorphous coat layer (12) over a substrate (10) such that Ni particles (13) and crystallized compounds (14) of Ni and P are produced locally and only on the surface of the coat layer (12) and along grooves (17) formed by abrading. Mechanical strength and anti-corrosive property of the coat layer can thus be maintained, and ferromagnetic materials can be affixed thereon and can be magnetized in a desired direction.
