Molecules containing both N and S have good inhibition property when compared with molecules containing only N or S. A good inhibitor of corrosion should be alkaline. Azole drugs such as Fluconazole, Ketoconazole and Clotrimazole are good corrosion inhibitors due to the presence of aromatic rings, hetero-atoms and alkaline character. The rate of corrosion and inhibition efficiency of mild steel in the absence and presence of Fluconazole (FA) and Zn2+ containing 60ppm chloride ion has been studied by mass loss method. The inhibition efficiency of the system with 220ppm FA and 50ppm Zn2+ was high. AC impedance spectra, polarization study, Fourier Transform Infra Red spectra were analysed for knowing the nature of protective coating formed. Copyright@ International Science Community Association
