, and ZSimpWin 3.2 software was used for the data fitting of impedance spectra. The potentiodynamic polarization curves of the samples in each period of immersion time of 0.5, 12, 72 and 192 h were recorded...). In corrosive environments, the existence of these electrochemically differentiated zones gives rise to localized corrosion phenomena. 3.2 Electrochemical measurements 3.2.1 Potentiodynamic polarization curves......

(XPS); Three-sweep potentiodynamic polarization measurement was employed to value the aqueous corrosion resistance of zirconium in a 0.5mol/L H2SO4 solution. It was found that a remarkable decline... zirconium is discussed. Key words:zirconium; corrosion resistance; cerium ion implantation; potentio dynamic polarization; X-ray photoelectron spectroscopy (XPS); [全文内容正在添加中] ......
investigated by cathodic polarization curve measurement. The surface composition and electronic properties of the pretreated and PP film coated metal surfaces were also characterized by XPS... a 13.56MHz radiofrequency generator. The polarization curve of PP film coated samples was measured in NaCl aqueous solution. The weight loss rate calculated from the value of the corrosion current......
