摘要
利用电化学工作站,通过改进使用电位阶跃法(计时电流法),以常用合金材料Alloy600、Alloy690和X80钢为研究对象,通过实验和理论分析来研究它们在不同溶液、不同温度条件下的腐蚀情况。研究结果表明,X80钢产生的极化电流较Alloy690、Alloy600要大很多;常温下Alloy690、Alloy600产生的氧化膜主要成分为Ni O,而X80钢产生的氧化膜主要成分为Fe2O3。
In this paper,having the electrochemical workstation employed,the potential step method（chronoamperometry,CA） improved and commonly-used Alloy600 and Alloy690 materials and X80 steel taken as the objects of study,their corrosions in different solutions and at different temperatures were experimented and theoretically analyzed. The results show that,the polarization current produced by X80 is much larger than that of Alloy690 and Alloy600; and the main constituent of the oxide film produced by Alloy 690 and Alloy600 at normal temperature is Ni O while the main component of the oxidation film produced by X80 steel is Fe2 O3.
