Abstract

Q235 steel samples were buried for one year in soils of test sites in 100 substations, which distributed at different areas in Anhui province presenting various typical soils of peculiar characteristics and meteorological conditions. Afterwards, the corrosion rates and corrosion products of the test samples were assessed via mass loss measurement, SEM, EDS and XRD. The results showed the rust scales formed on the samples were composed mainly of Fe₃O₄, Fe₂O₃, γ-FeOOH and α-FeOOH, but their relative amount varied by different soil test sites. The S^2- content in the soils of some soil test sites is high enough to generate FeS as the corrosion product of the samples. It indicates that the physiological activities of microorganisms have an effect on the soil corrosion behavior of the Q235 steel. In general, according to the test results from several typical soil test sites of Anhui province, Q235 steel samples present an average soil corrosion rate of 0.053 mm/a, and their corrosion grades are mostly “moderate”. The soil test sites where the samples have a high corrosion rate are mainly located in the areas along the Changjiang River and/or the industrial pollution areas. In terms of the Spearman correlation analysis, the correlation degree sequence of the index of soil texture and soil physicochemical properties affecting the one year soil corrosion behavior of the Q235 steel is: pH value > soil texture > soil resistance > salt content > water content > redox potential > Cl^- concentration.

Key words: power grid grounding material soil corrosion corrosion characteristic correlation analysis
