The paper describes the study of corrosion kinetics of marine structures for underwater technical facilities on the basis of new components having the ability to work effectively in the sea water environment and provide a qualitative increase in reliability. The effects of the sea water salt composition including mainly chlorides and sulfates of sodium, magnesium, calcium and potassium are studied. It is shown that due to the high content of chlorides, seawater is characterized by high ability to depassivate metals. The rate of metal corrosion in seawater is influenced by a number of factors. It was found that the general salinity of sea water does not strongly affect the intensity of the corrosion process, while some deviations from the usual composition can make the corrosion rate higher in several times.
