| 英文摘要 | Ti-9Mn alloy, widely used in aerospace and hydrogen storage, was recently introduced for marine and offshore structures because of its competitive mechanical characteristics. In this study, passive behavior of Ti-9Mn alloy was compared to the commercially pure titanium (cp-Ti). Ti-9Mn exhibited lower charge-transfer resistance than cp-Ti. Under steady-state condition, resistivity at metal/oxide film interface for Ti-9Mn alloy, which increased as fa unction of applied passive potential in range of 0.5 to 1.5 VSCE, was found to be lower than that of cp-Ti. Complex-capacitance (C infinity) value for Ti-9Mn alloy was higher than that of cp-Ti. Presence of Mn in the alloy induced significant increase in current density when potential exceeds 1.5 VSCE. Corrosion current density of Ti-9Mn (16.2 +/- 4.0 nA cm-2) was three times higher than that of cp-Ti (4.57 +/- 0.7 nA cm-2) after 21 days immersion in 3.5 wt% NaCl. The study may allow us to realize the full potential passivation behavior of Ti-9Mn for future marine and offshore applications. Ti-9Mn alloy was characterized by sharp increase in current density when potential exceeds 1.5 VSCE. Presence of Mn in the alloy decreased film growth rate, and lower charge-transfer resistance. The beta phase, enriched in Mn, was preferentially oxidized. |
