钢接地体在降阻剂中腐蚀速率测量方法的研究

orrosion rates of carbon steel electrodes in resistance reducing agents (RRA) were measured by means of methods of electrochemical linear polarization and inductance probe respectively. The acquired data were compared with those measured by mass loss methods by the same test condition. The results indicate that the accurate corrosion rate can be acquired by electrochemical means only when the measurement was performed at a time after the entire cure of the RRA, otherwise the given corrosion rate would be higher; both methods of the electrochemical linear polarization and inductance probe are effective and fast means to evaluate the corrosivity of RRA in the practice.
