Description
Summary:The corrosion of metal structures in large facilities such as AC power transmission lines results in economic losses due to the necessary replacement of these structures and the interruption of power supply. To evaluate soil corrosion of the buried part of the structure the corrosion rate of AISI1020 steel samples was determined by weight loss measurements as a function of the exposure time to the soil close to a power transmission tower. The same measurements were made with samples which were connected to the tower while buried in the soil. By comparison of the two measurement series the influence of the AC power signal on soil corrosion can be studied.
