Item type:Publication, Reflectivity from electrochemically protected Nb surfaces(Engineering Society of Corrosion, 2015-06-15)Corrosion resistance of fine mechanically polished and electro-polished Nb surfaces were tested by elliposmetric measurements the reflectivity at various angle of incidence. The same measurements were also repeated on electro-polished Nb surface anodic ally oxidized in 1M H2SO4 during 30 s in the potential/voltage range from 0 to 100 V. From the minimum value of measured reflectivity parallel to plane of incidence, the Brewster angle for each investigated sample was determined. The simultaneous measurements of corrosion parameters Brewster angle have shown that the values of Brewster's angle should be used for fast testing the quality of protected metal surfaces. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Photoelectrochemical Study of Anodically Formed Oxide Films on Niobium Surfaces(CROATIAN CHEMICAL SOC, 2010-07)The semi-conducting properties of electrochemically formed oxide films onto Nb surface in 1 M H(2)SO(4) have been studied by photo-electrochemical measurements. By cyclic voltammetry the I vs. E profile of active/passive transition of Nb electrode has been recorded in the potential region from -0.5 to 8 V (SCE). The photocurrent maximums, band gap energies and flat potentials of anodic oxide films formed by stepwise rising of anodic voltage from 10 to 100 V on Nb electrode have been determined. Using Raman spectroscopy the development of crystalline structure in the films with different resultant thickness has been analysed. The semi-conducting properties of niobium oxides with development of crystalline structure have been discussed in term of breakdown processes in the films. The thresholds of transition from amorphous to crystalline form of anodic oxide films depending of applied voltages and time of polarization have been determined. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Electrochemical behavior of tantalum in potassium hydroxide solutions(International Association of Physical Chemists (IAPC), 2018-08-31)The electrochemical behavior of tantalum in various concentrations of KOH solutions (0.1 M -10 M), was investigated using the evolution of the open circuit potentialin time, cyclic voltammetry and ellipsometricmeasurements. Depending on KOH concentrations, the open circuit potential measurements have shown three distinct behaviors concerning oxide film formation on the electrode surface and its dissolution. The cyclic voltammetry measurements were performed in various potential ranges, from -1.4 to 8 V, different concentrations of KOH solutions (0.110 M) and sweep rates ranging from 0.005 V/s to 1 V/s. In the passive region, very stable passive films were formed, which reduction has not been possible during cathodic polarization even at highly concentrated KOH solutions. In the trans-passive region, the very strong peak at 1.65 V was monitored, which nature and chemical composition is still not well known. - Some of the metrics are blocked by yourconsent settings
