【 摘 要 】

Corrosion behavior of brass electrode in TiO2nanofluids was analyzed using electrochemical impedance spectroscopy. The experimental results show that TiO2nanoparticles promote corrosion of brass. The corrosion resistance of brass electrode decreases with the increase of the temperature of the TiO2nanofluids. Sodium dodecyl benzene sulfonate (SDBS) is a dispersant in nanofluids and also appears corrosion inhibition to brass, and the corrosion inhibition enhances with the increase of SDBS concentration. The corrosion resistance of brass in TiO2nanofluids would decrease when the concentration of dispersant SDBS exceeds a certain value.
