| Abstract: | Изучено влияние состава и рН водной среды на коррозионное разрушение предварительно холоднодеформированной углеродистой стали. Получены количественные характеристики скорости электрохимической коррозии, которые следует учитывать при конструировании изделий из изученных материалов и назначении эксплуатационных требований к ним. |
| Description: | During operation there is interact of wire and wire products with various aggressive mediums, so it is important to know to what extent the consequences of cold deformation effect on interaction of the deformed metal with an aqueous medium of varying acidity and composition. The purpose of this work is to measure the hereditary susceptibility for electrochemical destruction of cold high-tensile wire due to the type, origin and aqueous medium corrosive acidic. The samples of wire from steel 85 (0,83% of carbon) dia. 2 mm and a length of 30 mm with degrees of pre-deformed by cold plastic deformation to 0 - 75 % were used in the experiments. To simulate the acidic media used 5% solution of sulfuric acid in distilled water, to simulate a neutral media - water of natural water sources. Noteworthy is the fact that the rate of corrosion in acidic media of three orders of magnitude higher then speed in neutral media. For small degrees of deformation higher corrosion resistance exhibit samples in media with large pH, but with increasing degree of deformation shown an inverse relationship, but with increasing of time delay differences in the rate of corrosion in aqueous media are disappeared. |
