In this paper, the magnesium alloy NZ30K alloyed with 0.1 wt. % Ag and clad with a 900 nm thick silver layer. It has been found that in the Ringer-Locke solution, the cylindrical sample underwent contact corrosion over the entire surface and crevice corrosion at the transition from the cylindrical to the flat part, which caused the coating delamination from the alloy under the mechanical action of hydrogen "bubbles" formed at the cathodic areas and corrosion products in the crevice, which have a higher specific vo...
