Acid solutions in modern industry are widely used at oil-and-gas facilities, metallurgy, housing-and-communal services, where they can be in contact with metal parts of industrial equipment for a long time, without the use of additional protection measures, causing its destruction. The specificity of the corrosive effect of acid solutions on metallic materials is analysed. Various groups of metal corrosion inhibitors (CIs) for these media and the features of the mechanism of their protective action were discussed. Among the various groups of CIs that protect metals in acidic media, various azole derivatives deserve the most attention. The industrial use of azoles is promising in the form of mixtures with other compounds. Promising lines of research in the field of inhibitory protection of metals in acidic media are associated with the wider application of the possibilities of electrochemical methods (voltammetry and electrochemical impedance spectroscopy). When determining the thermodynamic parameters of CIs adsorption, one should be guided by determining their true values, and not effective values. In the development of mixed CIs, a thorough theoretical study of these issues is required, taking into account prospects of such developments for the industrial use. Prospects for the industrial application of environmentally friendly («green») CIs for the protection of metals in acidic environments are considered. At present, the practical application of such products is limited by the lack of data on their compliance with the tight requirements of modern industries for CIs. The bibliography includes 129 references.","PeriodicalId":310379,"journal":{"name":"Corrosion: Materials, Protection","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134562622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accumulation of Fe(III) salts in acid solutions during their operation at metallurgical, oil and gas enterprises, objects of housing and communal services is a result of dissolution of mineral deposits, scale, thermal scale, and rust containing Fe (III) compounds in them. In addition, additional oxidation of Fe(II) salts in acid solutions to Fe(III) compounds is possible. The effect of the redox potential, determined by the ratio of the content of Fe(III) and Fe(II) cations in them, as well as mobility of Fe(III) cations, on the corrosivity of the systems under consideration was examined. The reasons for the accelerating and retarding action of Fe(III) salts on corrosion of steels in acidic media were analyzed. Modern concepts of the mechanism of corrosion of steels in these environments are discussed. The low efficiency of the inhibitory protection of steels in mineral acids containing Fe(III) salts is demonstrated. It is noted that it is possible to increase the protective effect of some corrosion inhibitors (CI) in these environments by reducing their overall aggressiveness. It can be achieved by introducing H3PO4 into them, which is capable of binding Fe(III) into strong complexes that have a lower oxidizing capacity than Fe(III) aqua complexes and mobility in an aggressive environment. The CI used in an aggressive environment must be effective in slowing down not only the cathodic reduction of protons and anodic ionization of iron, but also significantly suppress reduction of Fe(III) cations, which is realized with the diffusion control. These requirements are met by composite CI based on triazoles, which in H2SO4 + H3PO4 and HCl + H3PO4 solutions containing Fe(III) salts are effective in slowing down the corrosion of low-carbon steel.","PeriodicalId":310379,"journal":{"name":"Corrosion: Materials, Protection","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126528767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
