Photochemical Machining of Metallic Glasses (Amorphous Alloys) in Ferric-Chloride-Based Etchants
Winter 1986
Metallic glasses (Amorphous alloys) have recently been
developed with improved mechanical and magnetic properties
compared with conventional crystalline materials (see Tables 1
and 2 respectively). Metallic glasses cannot be stamped easily as
tooling is worn rapidly and consequently photochemical
machining (pcm) is a recommended fabrication method for
such devices as magnetic recording head and core laminations.
