摘要
利用电化学测试仪Model273A测试了Ta和Ta-2.5W在温度为60℃,浓度为30%,60%和80%的硫酸溶液中的Tafel曲线和动电位扫描阳极极化曲线。结果表明,在3种浓度的硫酸溶液中,Ta-2.5W的腐蚀倾向小于Ta的腐蚀倾向,腐蚀电流密度比Ta的小,钝化性能比Ta的优越。
In this paper, We tested the Tafel curves & anodic polarization curves of Ta and Ta-2.5W Mloy in 30%, 60% and 80% sulfuric acid solution at 60℃ temperature. The results showed that, in the three kinds of sulfuric acid solution, the corrosion tendency & corrosion electrical current density of Ta-2.5W alloy is less than those of Ta, and the passivation property of Ta-2.5W alloy is better than that of Ta.
