Comparison of the Corrosion Behavior of Brass in TiO(2) and Al(2)O(3) Nanofluids
The corrosion behavior of brass in TiO(2) and Al(2)O(3) nanofluids using a simulated cooling water (SCW) as the base solution and sodium dodecyl benzene sulfonate (SDBS) as the dispersant was studied by electrochemical measurements and surface analysis in this paper. It was found that SDBS could be...

description | The corrosion behavior of brass in TiO(2) and Al(2)O(3) nanofluids using a simulated cooling water (SCW) as the base solution and sodium dodecyl benzene sulfonate (SDBS) as the dispersant was studied by electrochemical measurements and surface analysis in this paper. It was found that SDBS could be adsorbed on the brass surface to form a protective film and have a corrosion inhibition effect on brass in SCW. In the SCW-SDBS-TiO(2) nanofluid, some negatively charged TiO(2) nanoparticles were attached to the brass surface and no obvious SDBS adsorption film was found, and the SDBS in this nanofluid had almost no corrosion inhibition on brass. In the SCW-SDBS-Al(2)O(3) nanofluid, the brass surface was covered by a uniformly distributed SDBS film containing some Al(2)O(3) nanoparticles which were positively charged, and the corrosion inhibition of brass was significantly improved in this nanofluid. It is concluded that the adsorption of SDBS on the brass surface in nanofluids is related to the charge status of the nanoparticles, which makes brass have different corrosion resistance in various nanofluids. |
