| 中文摘要 | Cu50Zr40Ti10 (at%) glassy ribbon was prepared by melt spinning. The effect of mechanical tension on its thermal and corrosive properties was investigated by differential scanning calorimetry and electrochemical polarization experiments, respectively. After mechanical tension, the crystallization temperature and the crystallization enthalpy almost maintain the same, while the relaxation temperature and the glass transition temperature decrease. In addition, the activation energy of the glass transition decreases from 74.8 +/- 1.7 KJ mol(-1) to 71.0 +/- 1.9 KJ mol(-1). The activation energy of the relaxation decreases from 70.0 +/- 4.4 KJ mol(-1) to 50.5 +/- 3.8 KJ mol(-1) at low heating rate, while increases from 186.1 +/- 9.4 KJ mol(-1) to 289.4 +/- 9.4 KJ mol(-1) at rapid heating rate. On the other hand, corrosion potentials polarized in all studied solutions sharply decrease, while the corrosion current densities increase. The pitting corrosion vanishes in 1 M chloride-containing solutions. The passive potential and the passive current density both decrease in 0.5 M H2SO4. The corroded surface micrographs in all studied solutions remarkably change. In addition, the difference of corrosive behavior in 0.5 M H2SO4, 1 M HCl, and 1 M NaCl is also discussed.
