Corrosion behaviors of Fe(45-x)Cr(18)Mo(14)C(15)B(6)y(2)M(x) (M = Al, Co, Ni, N and x=0, 2) bulk metallic glasses under conditions simulating fuel cell environment

Abstract

The corrosion properties of the Fe(45-x)Cr(18)M0(14)C(15)B(6)Y(2)M(x) (with M=Al, Co, Ni, N and x=0, 2) bulk metallic glasses have been investigated in a 1 M H2SO4+2ppm F- solution at 80 degrees C with H-2 and air bubbling, which simulate environments of the polymer electrolyte membrane fuel cell. The partial replacement of 2 at.% Fe led to significant modification of the corrosion behavior and resulted in corrosion resistances superior to that of stainless steel. (C) 2006 Elsevier B.V.
