ABSTRACTMS THESISINVESTIGATION THE INFLUENCES OF DIFFERENT ELECTRODES(Fe,Fe/Ni,Fe/NiZn, Fe/NiAl) OF HYDROGEN GAS EVOLUTIONÜmit TÜRKMENDEPARTMENT OF CHEMISTRYINSTITUTE OF NATURAL AND APPLIED SCIENCESUNIVERSITY OF CUKUROVASupervisor: Asst.

Prof. Faruk KARADAĞIn this study, hydrogen gas evolution has been studied in %3,5 NaCl solutionat bare mild steel and electrodeposited nickel, nickel-zinc, and nickel-aluminum onmild steel electrodes. For this purpose, cathodic polarization curves and Nyquistplots at different hydrogen evolution potentials obtained using three-electrodetechnique. To obtain hydrogen over potentials for these electrodes, electrolysissystem has been used. In addition, the hydrogen gas volume was measured evaluatedfrom the cathode at constant 3 V potential using electrolysis systems. From obtainingresults, hydrogen over potential decreased at electroplated nickel, nickel-zinc, nickel-aluminum electrodes.Key Words: Hydrogen, Nickel Coating, Nickel-Zinc Coating, Nickel-AluminumCoating, Over Potential, AC ImpedansII
