Inhibition of Al 7075 corrosion in Arabian Sea water using Cetirizine drug as a corrosion inhibitor

Pruthviraj R D*, Ramesha S and Vishwanath

The inhibition of Cetirizine drug on corrosion of Al 7075alloy in Arabian sea water medium became investigated
by way of weight reduction measurement, Tafel Polarization, and Electrochemical Impedance Spectroscopy (EIS)
techniques. The electrochemical outputs proved that the prepared Drug act as powerful corrosion drug. The outputs
found from electrochemical, weight loss and Electrochemical Impedance Spectroscopy (EIS) studies showed exact
consistency. The Present paper involves the examine of weight loss, Tafel polarization, EIS and microstructural
behavior of Al 7075alloy with and without drug. The corrosion research for Al 7075 has been executed with the aid
of using electrochemical analyzer in Arabian sea water medium at different temperature with and without organized
drug. From microstructural research, intergranular corrosion with lines of pitting was observed within the samples while
immersed in the Arabian sea water solutions without drug.
