中文摘要: 采用极化曲线和交流阻抗谱研究了苯并三氮唑(BTA)对黄铜/模拟水腐蚀体系的缓蚀作用,以及电磁场作用下BTA对黄铜电极缓蚀性能的变化.结果显示,BTA对该体系有较好的缓蚀作用;电磁处理和BTA联合作用时,腐蚀电流密度较缓蚀剂单独作用时进一步下降;电磁处理促进了缓蚀剂BTA在金属表面的吸附;在一定时间范围内,磁处理时间越长,BTA对黄铜电极的缓蚀性能越好.

Abstract:Corrosion inhibition of BTA to brass/simulated water system and the influence of electromagnetic processing to corrosion inhibition is carried out by using polarization curves and Electrochemical Impedance Spectroscopy.The results show that BTA has good corrosion inhibition to the system;compared with BTA treatment,the corrosion current densities decreases further after BTA and electromagnetic treatment.Electromagnetic processing promotes the adsorption of BTA on the surface of brass.During the electromagnetic processing,the longer time treatment is,the better corrosion inhibition performance within a period of time.
