CORROSION-RESISTANT AND WEAR-RESISTANT AMORPHOUS ALLOY AND A METHOD FOR PREPARING THE SAME

摘要

: Corrosion-resistant and wear-resistant amorphous alloy and a method for preparing the same There are disclosed a corrosion-resistant and wearresistant amorphous alloy characterized by having, on the surface thereof, an oxide layer including a crystalline oxide and a method for preparing the same characterized by carrying out the oxidation treatment of the amorphous alloy at a high temperature and at a high pressure in order to form an oxide layer including a crystalline oxide on the surface of the amorphous alloy. The amorphous alloy according to this invention possesses a remarkable corrosion resistance and wear resistance and had an improved magnetic permeability in the mega-Hertz zone.
