摘要

穆斯堡尔效应(M?ssbauer Effect)是一种固体中原子核对γ-射线的无反冲共振吸收或发射的现象,即γ-射线的共振荧光现象。利用穆斯堡尔谱研究腐蚀过程和腐蚀产物,近年来越来越受到国内外有关学者的重视(Meisel,1980)。穆斯堡尔谱是一种非破坏性结构测试手段,它不仅能研究晶态产物,也能研究非晶态产物,比X衍射等方法优越得多(夏元复等,1984)。自70年代末起,国内外开始出现一些关于海水中钢铁腐蚀产物研究的报道(Peev,1978;马如璋等,1981;吴继勋等,1982;陈俊明等,1982;郑裕芳等,1983),而用ME对在整个海洋环境中各个不同腐蚀区带钢铁的腐蚀产物的研究迄今还尚未见报道。作者于1994年10月在埕岛海区对挂片的腐蚀锈层的结构组成进行了穆斯堡尔谱分析,以探讨在各不同区带的腐蚀产物的差异及腐蚀机理,为开发耐海水腐蚀钢和普碳钢的防腐提供了理论依据。

Abstract

The phase composition of the rust layer of carbon steel (A steel) in the various corrosion zones in marine environment was determined by M?ssbauer spectroscopy for the first time.The inner and outer layer rusts of A; steel in the same corrosion zone have similar composition. With the exception of seawater, apparently the layer of rust in the various corrosion zones basically consist of α-Fe3O4 (A) α- Fe3O4 (B), α-FeOOH, β-FeOOH and α-FeO. Moreover. the rusts in the splash zone and tidal zone play a part in the cathodic process, so the corrosion rate of carbon steel is greatly accelerated by the wet/dry cycles.
