“…Studies to determine the corrosion rate were carried out according to the standard method given in the scientific literature [14,15,16]. To do this, unpainted samples of steel 08 kp with dimensions of 30×100×0.8 mm were placed in a sodium chloride solution and in RSE.…”

The article considers the processes of corrosion of the vehicle body influenced by road pollution components. It is noted that the support frameworks, especially their bottom, are most susceptible to corrosion damage. This is due to the presence in such bodies of seams, gaps, as well as hollow elements (spars, amplifiers, thresholds), which create favorable conditions for the occurrence and development of corrosion processes. A decisive role in this process is played by aggressive pollution of the road surface. The study of samples of the road surface of the highway has showed that they mainly include the following components: ammonium ions NH4+, sulphates SO42–, chlorides Cl–, nitrates NO3–. When assessing the corrosivity of the road surface pollution, comparative studies were carried out with sodium chloride solution, which showed that the road simulating environment (RSE) is equivalent in corrosivity to 5 % aqueous solution of sodium chloride. Experimental data on the dependence of steel corrosion in selected media on the duration of exposure and aeration of solutions are presented. Aeration of solutions increases corrosion losses of steel by 37.50% in sodium chloride solution and by 64.20 % in RSE. Kinetic equations for the dependence of the corrosion rate on time are derived. A hypothesis has been put forward that it is possible to effectively protect vehicle bodies from corrosion with the help of inhibitors with the addition of nanoparticles (NPs). In this regard, potassium monoborate (PMB) and PMB + titanium dioxide nanoparticles were studied as a corrosion inhibitor in RSE. It has been experimentally proven that PMB reduces the corrosivity of RSE, and titanium dioxide NPs enhance this effect. This composite can be recommended as an effective anti-corrosion additive.

“…In parallel, the iron cations produced by the corrosion are hydrolyzed, releasing hydrogen ions, which, together with the chloride ions, form strong electrolyte HCl, fullydissociated, which leads to a local decrease in pH within the pit. Decrease of pH forces other inclusions to be dissolved, releasing their own metal cations, which in turn can be hydrolyzed, releasing additional hydrogen ions, in addition to other highly aggressive products (NH 3 , H 2 S, silicic acid H 4 SiO 4 ,...), which contributes to the acceleration of localized corrosion and corrosion under solid deposits, since ammonia can combine with HCl to form the aggressive ammonium chloride NH 4 Cl [30,31].…”

The damage caused by crude oil impurities is in no way proportional to their small amounts, because there is an integrated system based on chemical composition and structure, chemical and electrochemical nature of corrosion processes, as well as sequence and synchronization between various damage mechanisms. Study of the influence of the heterogeneous metal content of the organic phase or steel matrix on premature failure of steel coils and equipment in oil refineries due to its aggressive role in corrosion processes allows us to reach certain rate-limiting stages of corrosion, which can help us describe better solutions to protect them against corrosion and premature failure. Industrial problems at which multiple sciences intersect represent challenging research tasks. On the other hand, solving them is as difficult as it is, as much as it adds wider interconnection between the various sectors of science, which would provide a clearer and deeper understanding to the problems faced by researchers that contributes to a multidimensional scientific-industrial development.
