INVESTIGATION OF THE INFLUENCE OF MOISTURE MOISTURE ON ITS CORROSIVE AGGRESSION
Journal Title: Енергетика і автоматика - Year 2018, Vol 0, Issue 3
Abstract
The results of studies on the determination of soil electrical resistivity as a function of soil moisture are presented, which is an important factor in soil corrosion of metals. On the basis of classification of corrosion activity of soils on a five-point system, a relationship was established between the degrees of corrosive activity and soil moisture by the example of loam and sand. Objective – investigation of the influence of soil moisture on the corrosive aggressiveness of the soil. The theoretical and experimental component of electrochemical studies was carried out at the installation to determine the value of the specific electrical resistance of the soil in laboratory conditions according to the electrical scheme in accordance with GOST 9.602 - 2016. It is determined that an increase in the moisture content of sand from 10 to 40% practically does not cause an increase in corrosion rate, corrosion activity is low. For loam already at a humidity of more than 10%, corrosion activity progresses from low to high. At a humidity of the order of 30-40%, the maximum rate of the corrosion process is observed.
