摘要
The immersion corrosion of archaeological iron in solution(0.06mol·L- 1NaCl+0.03mol·L -1 Na2SO4+ 0.01mol·L- 1 NaHCO3)simulating soil water composition was presented.The evolution of archaeological iron from iron to iron oxide and to iron oxy-hydroxides compounds was investigated by scanning electron microscope(SEM) and X-ray diffraction(XRD)analysis.According to the morphology,phase composition,and transformation proc- ess,the contributions of each corrosion product to archaeological iron were discussed.
