In this paper, we systematically demonstrate the corrosion behavior and surface characteristics of a newly developed Cu36Zr48Ag8Al8 bulk metallic glass (BMG). The Cu36Zr48Ag8Al8 BMG exhibits excellent corrosion resistance in acidic and alkaline solutions without Cl ions. The alloy is spontaneously passivated with a markedly low current density in 1 N H2SO4 solution. The formation of the bilayered passive film of the present alloy immersed in 1 N H2SO4 solution, which is composed mostly of Zr4+ cations in the exterior part and Zr4+- and Al3+-enriched cations in the inner part, could be responsible for the high corrosion resistance.
