摘要:利用CHI660B电化学工作站替代恒电势仪,采用线性扫描法测定碳钢在碳酸铵溶液中的钝化曲线,结果显示:该方法与传统测定方法相比,具有操作简便、灵敏度和精度高、数据处理方便等优点.

关键词: 物理化学实验, 钝化, 教学改革

Abstract: The passivation curves of carbon steel in ammonium carbonate solution  are  determined by linear sweep voltammetry method with electrochemical work station of CHI 660 B to replace potentiostatic meter.Compared with the traditional method,this method has some advantages such as easy operation,high sensitivity and precision,convenient data processing.

Key words: physical chemistry experiment, passivation, teaching reform
