Abstract

The corrosion inhibition effect of Ethyl-2-phenyl hydrozono-3-oxobutyrate (EPHO) and 2-chloro-1-benzothiophene-3-carbohydrazide (CBTC) on 6061 Al alloy/SiCp composite in 1 M hydrochloric acid solution at 30, 40, 50 and 60 °C has been investigated using potentiostatic polarization technique and weight loss method. Both EPHO and CBTC are efficient cathodic inhibitors with 82 % and 88% inhibition efficiencies. The adsorption of the inhibitors on the composite surface was found to obey Langmuir adsorption isotherm and the inhibition is governed by mixed adsorption mechanism
