Corrosion behaviors of Fe45−xCr18Mo14C15B6Y2Mx (M=Al, Co, Ni, N and x=0, 2) bulk metallic glasses under conditions simulating fuel cell environment

The corrosion properties of the Fe 45-x Cr 18 Mo 14 C 15 B 6 Y 2 M x (with M=Al, Co, Ni, N andx=0, 2) bulk metallic glasses have been investigated in a 1 M H 2 SO 4 + 2 ppm F - solution at 80 °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.
