Effect of Pyridine on the Corrosion Behavior of Electrodeposited Ni-Co Alloy Thin Films and Their Structural and Morphological Analysis
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 5
Abstract
Ni-Co thin films have been grown on Stainless steel substrate by galvanostatic electrodeposition from Sulphate baths containing Pyridine as Organic inhibitor. A comparative study of corrosion parameters were done in three different electrolytes; NaCl, HCl, H2SO4 by tafel extrapolation method. Pyridine is found as an effective corrosion inhibitor for Ni-Co alloy thin films and showed minimum corrosion rate in NaCl medium. The morphology and structural analysis of thin films were done by Scanning Electron Microscopy (SEM) and X-Ray Diffraction pattern (XRD), respectively. Elemental composition has been determined by Energy Dispersive X-Ray spectroscopy (EDAX). XRD confirmed that the films possessed a mixture of Cubic and hcp crystal structures.
