Abstract

A review of studies on the protection of metals and their alloys from corrosion has been conducted. Currently, the problem of protecting metals and metal structures from corrosion is relevant in the world. The problem of protecting metal products from corrosion has not lost its importance since the beginning of the use of metal. The urgency of this problem lies in the fact that the intensive development of metal-intensive industries is associated with the rapid growth of economic and environmental damage caused by the destruction of metal structures, equipment and products. Practically all existing metal is subject to corrosion, but the long-term reliable functioning of products, equipment, metal structures made of metal and its alloys depends on the speed of the corrosion process. The average service life of products made of non-ferrous and ferrous metal alloys is about fifteen years, which is common in environmental conditions. Not only iron alloys, but also hard-to-melt metals and their alloys have a harmful effect on the environment. The main harm from metal corrosion is associated not only with the loss of a large amount of metal, but also with the failure of metal structures, since due to corrosion they lose the necessary strength, ductility, density, thermal and electrical conductivity, insulation and other necessary properties. Protection of metal structures from corrosion gives a positive effect by reducing the cost of repair and complete replacement of the entire structure or part. Corrosion protection is one of the most important problems of modern industry. This article provides information about the origin of the term corrosion, the course of this process, its types and the alleged damage.
