It has been found out that a decrease in the oxidizing ability of such systems is observed with the simultaneous presence in their composition of phosphoric acid and urotropine. A decrease in the oxidizing ability of such systems is a result of the binding of Fe(III) in complex compounds with phosphate anions and urotropine. Such Fe(III) complexes have a low oxidizing ability. Inhibitory protection of steels in solutions of mineral acids, in the case of accumulation of an additional oxidizer, namely Fe(III) cations, is possible under the following conditions. First, the oxidizing ability of Fe(III) cations must be reduced by binding them in complex compounds by anions formed during acid dissociation. Individual H3PO4 or mixtures thereof with other acids can be used as such an acid. Second, it is necessary to use an effective inhibitor of acid corrosion, which is capable of simultaneously appreciable slowing down the reduction of protons and Fe(III) complex compounds with anions of acid residuals. Composite inhibitors based on triazole derivatives and sulfur-containing compounds correspond to this property.","PeriodicalId":310379,"journal":{"name":"Corrosion: Materials, Protection","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126762974","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 effectiveness of the protective afteraction of mixtures containing IFKhAN-92 is determined by the time of preliminary adsorption of the inhibitor, its concentration in the solution of preliminary adsorption, the temperatures of the solution of preliminary adsorption of the inhibitor and the background acid solution. The layers formed on steel by the IFKhAN-92 + KNCS and IFKhAN-92 + KI compositions have the highest protective afteraction. These layers protect steel at 80 °С in the background 2 M H2SO4. An increase in temperature of the solutions of preliminary adsorption of inhibitors enhances their protective afteraction, which indicates chemical nature of the interaction of the inhibitor molecules with the steel surface. The composition and the structure of the protective layers formed on the steel surface was studied by XPS analysis. The protective layer is chemically bonded to the phase of hydroxides and oxides of Fe, Cr and Ni, adjacent to the metallic phase. The lower part of the protective polymolecular layer of the organic inhibitor consists of a polymer complex formed by molecules of IFKhAN-92 and metal cations (Fe, Cr and Ni). The outer part of the protective organic layer consists of physically adsorbed molecules IFKhAN-92, easily removed from the metal surface during ultrasonic washing of samples.","PeriodicalId":310379,"journal":{"name":"Corrosion: Materials, Protection","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121396808","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}

It is shown that under experimental conditions the three-component inhibitor mixture provide protection of steel in 1 M HCl + 1 M H3PO4 even in the presence of Fe(III), Fe(II) salts or their mixtures. Under similar conditions in individual 2 M HCl the protective effects of inhibitors are lower. A stronger deceleration of steel corrosion by composite inhibitors based on IFKhAN-92 in HCl + H3PO4 solutions containing Fe(III) salts, in comparison with similar solutions of individual HCl, is largely due to the binding of Fe(III) cations by phosphate anions into complexes, which considerably reduces their chemical activity and, as a consequence, the steel corrosion rate.","PeriodicalId":310379,"journal":{"name":"Corrosion: Materials, Protection","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129592397","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}
