High-quality poly(p-phenylene) film prepared by electrochemical polymerization of benzene at a stainless steel electrode

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.

Capacitive Reactance

Severe corrosion phenomenon appeared in an expansion joint of blast furnace gas (BFG) pipeline after booster fan in a power plant. The sediment adhered to the inner wall of the expansion joint was analyzed by ion chromatography. The corrosion site of expansion joint was examined by scanning electron microscope (SEM), and the behavior of electrochemical corrosion of stainless steel electrode was discussed through electrochemical impedance spectroscopy (EIS) and polarization curve. The results reveal that the leaching solution of the sediment is a kind of strong electrolyte solution. Along with the increase of immersion period, the impedance of stainless steel electrode decreases dramatically, the impedance spectroscopy experiences such a procedure that a single capacitive reactance arc gradually develops into the contraction of inductive reactance and then tends to be two capacitive reactance arc, which indicates that pitting corrosion transfers from induction period to evolution period until metastable pitting translates into stable pitting. There exists no passive area in polarization curves of stainless steel and shows the characteristics of active dissolution. In conclusion, the failure of the expansion joint stainless steel shows typical pitting characteristic.
