Abstract: Substituting boron for carbon can improve the corrosion behavior of Fe-based amorphous significantly especially in acid solution with saturated H_2S. XPS analysis proves that boron enriches in the surface layer of amorphous and reacts with hydrogen to form B_(10)H_(14) . It efficiently prevents the intrusion of hydrogen to the sample, thus the destructive effect of hydrogen can be decreased greatly.

Key words: Fe-based amorphous, H_2S corrosion, boron
