| 中文摘要 | We studied the corrosion properties of bulk nanocrystalline 304 stainless steel (BN-SS304) produced by severe rolling technique and conventional polycrystalline 304 stainless steel (CP-SS304) with immersion test, X-ray photoelectron spectroscopy, ultra-violet photoelectron spectroscopy, inductively coupled plasma emission spectrometer, and scanning electron microscope. Immersion test was carried out in 0.5?mol?L-1 HCl solution for 30 days immersion interval at room temperature. It is well known that the pitting corrosion of stainless steel could be inevitable in solution containing Cl-. However, BN-SS304 can scarcely suffer from pitting corrosion with the compact oxide film on its corrosion surface and less corrosion rate in comparison with CP-SS304. The less corrosion rate of BN-SS304 was attributed to the stronger O2 adsorption and compact oxide film on its corrosion surface, its less weight of 4s4s valence electrons and its larger work function in comparison with CP-SS304. The improved pitting corrosion resistance of BN-SS304 resulted from the compact oxide film, weaker Cl- adsorption and less Cl- chemical activity on its corrosion surface. |
