Effect of Aquo-Glycolic Media of Anodic Oxides on Zr
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 2
Abstract
The surface of zircaloy-4 anodized at a constant current density of 4mA.cm ethylene glycol at a potential 0–187V, was characterized by means of surface science technique AFM with micro and nanostructures. It was found that d homogeneous coverage on zr-4 surface modifying the topography. The incorporation of oxalate dianions from the electrolyte and ethylene glycol solvent to the surface during the anod oxide films grown with relatively high voltages, the oxide formed over the Zr rougher and protruded. Anodic oxide films were homogeneous and rough with nanosized grains. When the anodization voltage was 187 V the average roughness (Ra) of the anodic film reached 5.9nm, and the oxide formed changed abruptly to become as rough as that formed
