摘 要: 本文通过一个简单的电化学试验研究了Hastelloy-B3(N 10675)在含Cl^-醋酸溶液中钝化膜自修复能力试验结果表明:随着浓度的增大和温度的升高,钝化电位(Eth)越小,钝化膜的自修复能力越强;B3合金由于Mo含量高,钝化膜自修复能力非常强,在含Cl^-醋酸溶液中具有很强的抗腐蚀能力。 The repassivation potential of Hastelloy-B3 in the Cl- containing acetic acid solution has been researched by a simple electrochemistry test. The results shows that the repassivation potential of Hastelloy-B3 increased with the higher concentration and temperature. The intensived corrosion resistant of Hastelloy-B3 in the Cl- containing acetic acid solution is due to high content of Mo in Hastelloy-B3.
