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。
The phase composition of the rust layer of carbon steel (A3 steel) in the various corrosion zones in marine environment was determined by Mossbauer spectros-copy for the first time. The inner and outer layer rusts of A3 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.
