potentiometric analysis meaning in Hindi

Examples

1. The corrosion behavior of nanocrystalline ( nc ) copper bulks with various grain sizes prepared from igc ( inert gas condemsation ) and vacuum annealing in comparison with conventional microcrystalline ( mc ) copper ( as - rolled and electrolytic ) in acid copper sulphate solution and neutral solution containing chlorides under free corrosion conditions and anodic polarizations has been studied using potentiodynamic polarization , potentiometric analysis , cyclic voltammetry and electrochemical impedance spectroscopy . x - ray diffraction was used to estimate the grain size of the annealed nc copper . field emission gun scanning electron microscopy and x - ray energy - dispersive spectroscopy was used to characterize the surface morphology and analyze the surface composition after the polarization and potentiometric test of both nc and mc copper
2. Cyclic voltammetry indicated that the reaction mechanisms of micro - and nc copper are identical , but the anodic peaks current density of nc copper is much lower than that of mc copper . the potentiometric analysis demonstrated that the pitting corrosion seemed to happen earlier on nc copper surface than on the mc surface . the xrd found cu2o on nc copper surface while no oxide was found on mc copper surface
