Abstract

The electrochemical corrosion behaviour of the synergistic effect of 4-hydroxy-3-methoxybenzaldehyde and 1, 4-diaminobenzene on mild steel in dilute sulphuric and hydrochloric acid solution (1M concentration) with 1.5% recrystallized sodium chloride evaluated with weight loss analysis, potentiodynamic polarization test and optical microscopy. Statistical analysis of the results was done with Two-way ANOVA to assess their statistical significance of the experimental variables on inhibition efficiency values. Results show the combined organic derivatives performed effectively in both acids with average inhibition efficiency values above 85%. Observations from optical microscopy images further confirm the results of experimental data. Statistical derivations reveal the overwhelming significance of exposure time only inhibition efficiency values in both acids.
