Corrosion control of glutaraldehyde biocide for 304 stainless steel in simulated cooling water system containing sulfate-reducing bacteria (SRB) was studied by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. The results revealed that impedance values of stainless steel electrode increased gradually while the passive current densities decreased with the increasing concentration of glutaraldehyde. The biocide improved good anti-corrosion performance to stainless steel in bacteria system. The impedance value |Z|0.05 increased from 19.72 kΩ·cm2 to 33.77 kΩ·cm2, and the passive current density reduced from 0.93 μA·cm-2 to 0.16 μA·cm-2 when the glutaraldehyde concentration reached 80 mg/L.

Abstract: The effect of electromagnetic treatment on corrosion behavior of carbon steel and stainless steel in simulated cooling water was investigated by electrochemical impedance spectroscopy, potentiodynamic polarization techniques and water analysis. It was found that the charge transfer resistance decreased and the corrosion current density increased after electromagnetic treatment for carbon steel electrode, which shows that such treatment promotes corrosion of carbon steel in simulated cooling water. In contrast, the pitting potential of 316L stainless steel electrode rose which revealed that electromagnetic treatment of the experimental water exhibited corrosion inhibition to 316L stainless steel. Reasons for different corrosion behavior of the two metals were discussed.

ABSTRACTCVD polycrystalline diamond surfaces were etched using reactive ion etching system with either a conventional stainless steel electrode or MgO sintered ceramic containing electrode. The micro-needle array of high aspect on diamond substrate surfaces obtained with MgO electrode was fabricated by using back-sputtering from MgO electrode. The RMS roughness of diamond substrate surfaces obtained with MgO electrode is higher than those obtained with stainless steel electrode.
