ABSTRACT:
An amorphous alloy article having solderability is obtained by subjecting an amorphous alloy article to an immersion treatment with an acidic activating bath comprising hydrochloric acid, citric acid, nitric acid, a nonionic or amphoteric surface active agent; electroactivating the amorphous alloy with a cathode-electrolytic bath comprising phosphoric acid, sulfuric acid, citric acid and a nonionic or amphoteric surface active agent; and immediately thereafter electroplating the electroactivated amorphous alloy with a metal selected from copper, nickel, tin, zinc and alloys thereof.
