Tensile effect on corrosive and thermal properties of Cu55Zr35Ti10 metallic glass

Cu55Zr35Ti10 (at%) glassy ribbon was prepared by melt spinning. The effect of the tension on its thermal and corrosive properties was investigated by differential scanning calorimetry and electrochemical polarization experiments, respectively. After the tension, the crystallization procedure including crystallization temperature and crystallization enthalpy of Cu55Zr35Ti10 metallic glass hardly maintains the same, while the relaxation temperature and glass transition temperature decrease. In addition, the activation energies of the glass transition and the relaxation decrease. On the other hand, corrosion potentials polarized in all studied solutions sharply increase, while the corrosion current densities decrease. The corroded surface micrographs in all studied solutions are remarkably changed. In addition, the difference of corrosive behavior in 0.5 M H2SO4, 1 M HCl, and 1 M NaCl is also discussed.
