The corrosion of glassy(Ni8Nb5)99.5Sb0.5 alloy was investigated in 1,6 mol/L HCl,1 mol/L H2SO4 and 3% NaCl solutions,respectively,by immersion tests and electrochemical measurements and compared with that of pure Ni,Nb and Sb.The stability of passive film was studied using potentiostatic current transients and XPS depth profiling.The surface morphology of the glassy alloy after electrochemical potentiodynamic polarization test was observed using SEM.The result indicates that the Ni-Nb-Sb alloy shows good co...
