摘要: 利用极化曲线、恒电位电流衰减测量以及慢应变速率拉伸试验等方法研究了低碳钢、16MnR和12CrlMoV低合金钢在铝酸钠溶液中的应力腐蚀规律。NaOH溶液中存在的AlO_2~-能抑制钢的阳极溶解;AlO_2~-对钢的应力腐蚀存在双重影响,即促进裂纹萌生,同时又对裂纹扩展起抑制作用。铝酸钢溶液中钢的抗应力腐蚀能力依次为12CrlMoV>16MnR>低碳钢。钢在热浓碱溶液中的应力腐蚀是存在碳化物活化途径和膜破裂机制联合作用的结果。

Abstract：SCC of mild steel, and 16MnR and 12Cr1MoV low alloy steels in caustic aluminate solution was invesigated by means of the slow strain rate technique The effect of AlO_2 anions on anodic dissolution was also studied It was found that anodic dissoiution of the above mentioned steels was inhibited and that their repassivation rate was reduced in the presence of AlO_2 in NaOH solutions. A dual influence of AlO_2 on stress corrosion behavior of the steels was observed. The addition of AlO_2 tended to shorten the period of time for crack initiation, whereas to retard crack propagation. 12CrlMoV steel exhibited the highest stress corrosion resistance of the three tested steels. All the results can be explained in terms of a combined action of pre-existing active and film-rupture model.
