Abstract

Annotation. Goal. The study of the corrosion properties of phosphonic acids in model solutions. Getting the patterns of change in the deep corrosion indicator of the concentration of the reagents administered compositions based on phosphonic acids. Obtaining the regression equation corrosion tests phosphonic acids. Methods. The corrosion rate was determined by gravimetric method in accordance with GOST 9.502-82. Processing the results of experiments carried out with the help of Microsoft Excel. Results. On the basis of these studies concluded that the use of mixtures of phosphonic acids efficiently than its individual components. This is explained by the phenomenon of synergism, as a phenomenon of mutual strengthening of certain compositions of the test reagent. Scientific novelty. Based on the studies developed compositions of environmentally friendly corrosion inhibitor compositions. Practical significance. Optimal compositions and concentrations of corrosion inhibitors on the basis of phosphonic acids. The equation of the regression of the deep changes the corrosion rate from the dosage mixture FBTK and HEDP.
