Abstract

One of the most effective means of protecting metalwork equipment premises from corrosion is currently zinc-plating. Zinc-plating increases the service life of the equipment by 2-3 times, i.e. up to 20 years, which makes this method economically justified.We measured the electrode potentials and corrosion current between two plates – steel and zinc, depending on the size of the zinc plate. Modeling of the corrosion process with a decrease in the zinc coating was carried out by reducing the area of the zinc plate. At the same time, the area of the steel plate was constant. The protective ability of the zinc coating is maintained as long as it occupies at least 10% of the surface area of the steel product. Reducing the area of the zinc coating leads to catastrophic corrosion failure of the coating.
