【摘要】 采用线性扫描伏安、塔菲尔曲线和交流阻抗法等电化学方法,研究了铁在不同实验条件下的腐蚀规律,计算得出相关腐蚀动力学参数。结果表明,酸性条件下,酸性越强,或碱性条件下,p H值越大,铁易腐蚀;在卤素离子的中性溶液中,Cl-溶液对铁腐蚀的影响最大,Cl-浓度越高,对铁的腐蚀有促进作用。更多还原

【Abstract】 Linear sweep voltammetry, tafel curves and electrochemical impedance spectroscopy were employed to measure the corrosion of the iron under different experimental conditions, which calculates the relative corrosion kinetics parameters. Under acidic conditions, the more acidic, or alkaline conditions, the results showed that the bigger the p H value can accelerate the corrosion of iron. Effects of Cl- about the corrosion of iron was the biggest in neutral solution of halogen ions, the higher concentration of Cl- can increase the dissolution rate of corrosion of iron.更多还原
