摘要：
Corrosion behavior of brass electrode in TiO2 nanofluids was analyzed using electrochemical impedance spectroscopy. The experimental results show that TiO2 nanoparticles promote corrosion of brass. The corrosion resistance of brass electrode decreases with the increase of the temperature of the TiO2 nanofluids. 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 TiO2 nanofluids would decrease when the concentration of dispersant SDBS exceeds a certain value.
