Abstract

An anomalously high rate of chloride deposition observed in Gelendzhik in February 2023 during the annual corrosion tests was investigated. An estimation of the threshold value of the chloride deposition rate on samplers corresponding to the rate of chloride deposition directly on the surface of metal samples is given. The correction of calculation of the average annual rate of chloride deposition ([Cl]) under anomalously high salinity of the atmosphere is proposed. Based on the average annual climatic parameters and [Cl] by dose-response functions the forecast of first-year corrosion losses of metals is made.
