The main process leading to the destruction of the cast elements of gas-collection bell of electrolyzer, made of grey cast iron, is the oxidation of iron by oxygen, SO2 gas and sulfur vapors to form magnetite, hematite and pyrrhotin. The simultaneous formation of iron oxides and sulfides does not prevent further corrosion, since scale is formed with a loose structure that does not have protective properties. Reducing the length of the interfacial boundaries inside the material of the cast enables to reduce the rate of corrosion destruction, which can be achieved by modifying the cast iron to change the shape of graphite inclusions, i.e. obtaining high-strength cast iron with a spherical shape of graphite inclusions. However, the obtaining spherical graphite in cast iron using magnesium modification does not exclude the access of aggressive gases to the surface of the products and the possibility of their diffusion along the grain boundaries. It was shown that alloying can be an alternative, which leads not only to the exclusion of lamellar secretions of graphite in the structure of cast iron, but also to the formation of surface oxide layers based on the alloying element preventing the corrosion. Alloying with chromium gives cast iron high abrasive resistance due to the presence of a carbide component in the structure, as well as corrosion resistance due to the alloying of the metal base, heat resistance due to increasing the electrochemical potential of the metal base and creating a strong neutral oxide film on the surface of the castings, heat resistance, etc. An experimental comparative analysis of the corrosion resistance of cast iron used for manufacturing of gas collecting bell of electrolyzers showed that chromic cast iron ЧХ3 has a higher corrosion resistance than high-strength cast iron with spherical graphite ВЧ50 and much higher than grey cast iron with lamellar graphite. However, chromic cast iron ЧХ3 has low casting properties, is very sensitive to the cooling rate and has a large heterogeneity in structure, which makes it difficult to use it for the manufacture of gas collecting bell of electrolyzers.

High-quality multicomponent diffusion boride and carbide layers on steel 40Cr and 25CrMnTi cemented steel were obtained by processing from 3 to 6 hours at 950 ° C in melts. The melts contained borax and ferroalloy additives. Chrome, vanadium and titanium were alloying elements. Comparative tests of heat resistance and corrosion resistance of diffusion coatings are carried out. Samples with carbide coatings Cr + V and Cr + V + Ti had the highest heat resistance. Samples with a diffusion layer based on iron borides and alloying elements showed the best corrosion resistance during long-term tests in a 10% HCl solution.

The solar selective absorbing coating is the key component of solar energy collector which determines the heat conversion efficiency. The coating materials mentioned in this paper were prepared by Al as substrate, Al2O3-Pt as absorbing layer and metal Ag as infrared reflector. We got three kinds of coatings by adjusting the magnetron sputtering process. Respectively testing and analyzing the performance and microstructure showed that element content of Al, N, O in the coating are of important influence on its performance, meanwhile, the better the crystallization of coatings surface, the more helpful to improve the performance of its corrosion resistance and its moisture and heat resistance.

Experiments were carried out on the heat resistance, corrosion-resistance and adhesion performance of the nano-modified urushiol titanium antiseptic paint on the top heat exchanger of Atmospheric Tower. Through the experiment, it can be found that the corrosion resistance in the environment of HCl-H2S-H2O can be effectively improved by adding a certain amount of nano-SiO2 into urushiol coating made of titanium the top heat exchanger of Atmospheric Tower for modification.
