Abstract

The results of a study of the susceptibility to crevice corrosion of aluminum alloys AMg6, D16-T and stainless steel 08X17 in tests in the natural sea water of the Black Sea are presented. The estimation of changes in appearance of samples, metallographic analysis and estimation of the degree of biofouling is carried out. Physico-chemical indicators of sea water, including those determined by capillary electrophoresis, are presented. The analysis of corrosion resistance tests in seawater, the features of the methodology for slit corrosion testing, and the mechanism of crevice corrosion formation are presented.
