Corrosion of mild steel by soils of Shelby County, Tennessee, and their infra-red spectra: A correlation study

From a study of the infra-red spectra of six soil types found in Shelby County, Tennessee, and the corrosion of mild steel in contact with the soils, it was found that strong relationships exist between the corrosion rate and the concentration of either Si-OH (absorbed water) or Al-O (alumina) species in a soil. It was concluded that either of these concentrations may be used as a predictor of the corrosivity of a soil. 5 refs., 1 fig., 4 tabs.
