| Abstract [eng] |
In this Master thesis, the process of corrosion in S235 structural steel in sodium chloride solution, technological condensate of industry, and ammonium hydrogen sulphide was studied. The process of corrosion was investigated by the use of linear polarization resistance method. Surface hardening of the structural steel samples for reducing the corrosion rate such as carburizing and annealing were used during the research. The process of corrosion in the aggressive media like the sodium chloride solution, technological condensate and ammonium hydrogen sulphide was reduced by using two inhibitors, CHIMEC 1839 and Stearin dissolved in Toluene. The hardness of the structural steel samples (annealed, carburized and nitrided) were measured using the Vickers Hardness testing machine and an analysis of each kind of sample with respect to their rate of corrosion in all of the aforementioned aggressive media was studied, leading to a detailed conclusion at the end. |
