Abstract
The electrochemical corrosion behaviour of n, n’-diphenylthiourea on the surface properties mild steel in attenuated sulphuric and hydrochloric acids (3M concentration) contaminated with 3.5% recrystalized sodium chloride at ambient temperatures was examined through weight loss analysis, open circuit potential monitoring and potentiodynamic polarization. The surface morphology of the samples was analyzed with scanning electron microscopy and x-ray diffractometry. Statistical analysis of the results was done with aid of ANOVA software to assess their statistical relevance. Results show the thiourea derivative performed more excellently in sulphuric than hydrochloric acid based on inhibition efficiency values. Observations from SEM/XRD image and data further confirm the results of experimental data. Statistical derivations reveal the overwhelming influence of exposure time on inhibition performance compared to concentration of the organic compound.
