3. Combating against (борьба против) the corrosion of metals has now become a key problem in all industrialized countries. The scientific and technical achievements in the field of raising the corrosion resistance of construction materials are the basis of technical progress in different branches of industry, an indicator of the country’s economic potential.

4. A large amount of “anti-corrosion” work is being carried out in Russia. The results are evident: Russian-made inhibitors (ингибиторы), изготовленные в России), varni​shes, paint covers are being well known throughout the world. Gas pipelines, metal structures, the bodies of atomic reactors and ships, etc. have been reliably protected against corrosion.
