Çeliklerin Korozyonuna Boraksın Etkisi

In this study, the effect of borax (Na 2 B 4 O 7 ) on the corrosion of Ç 1010, Ç 304 and Ç 316 steels was investigated. For this purpose, solutions with borax at different concentrations (0.0125 M, 0.025 M, 0.050 M and 0.100 M) were prepared. Cycling Voltammetry (CV) technique was used to determine the electrochemical behavior of steels in this environment, and Tafel Polarization Method was used to measure corrosion rates. As a result of the experiments, it was determined that the corrosion rate decreased and the corrosion potential increased in all three steels with increasing borax concentrations. Lowest corrosion rate at higest borax concentration was obtained from Ç 316. Corrosion rates of Ç 1010, Ç 304 and Ç 316 steels at 0,100 M borax concentration have been measured respectively as 0.251, 0.132 and 0.071 mm/ year. Borax protected steels from corrosion by showing anodic inhibitory behaviour. It is concluded that the steels can be used safely in borax solutions.
