一、前言采用电化学装置研究大气腐蚀现象和规律始于五十年代,随后加拿大 P.Sereda 采用腐蚀电池监测户外暴露的金属表面“湿润时间”取得了成功。七十年代,以瑞典 V.Kucera和美国 F.Mansferd 为代表,采用 Fe-Cu等双金属原电池,或阴阳极为同种金属外加电动势的电解电池,对大气腐蚀的电化学监测 I. INTRODUCTION The use of electrochemical devices to study atmospheric corrosion phenomena and laws began in the 1950s. Successively, P.Sereda of Canada used a corrosion cell to monitor the exposed metal surface of the cell. Seventies, Sweden V.Kucera and the United States F.Mansferd as the representative, the use of Fe-Cu and other bimetallic primary batteries, or the cathode is the same kind of metal plus emf electrolytic cells, the electrochemical monitoring of atmospheric corrosion
