英文摘要	Corrosion of metals induced by highly salinized soils will reduce service life of pipelines in Qaidam Basin. The corrosion behavior of cast iron in silty clay was investigated using electrochemical measurements, Scanning Electron Microscopy and X-ray Diffraction. The corrosion rate is proportional to water and salt content, with the maximum rate of 5.27% with salt content of 30%. The etch pits enlarge and grow in quantity. The conductivity of pore water dominates with water, and the more susceptibility of penetrating and film breaking appears with chloride concentration. The products hinder the oxygen transportation and corrosion rate reduces exponentially with time. (C) 2019 Elsevier Ltd. All rights reserved.
