Abstract

Aluminium matrix composites reinforced with silicon carbide have prominent properties which make them useful in several industries. Corrosion is a major problem in the use of Aluminium Matrix Composites reinforced with silicon carbide, which will be still severe in acid medium. Inhibition is one of the mechanisms used for mitigating the metallic corrosion especially in acid environment. A large number of organic heterocyclic compounds containing nitrogen, sulphur and oxygen have been used as corrosion inhibitors. In the present work an attempt has been made to study the inhibition effect of Ethyl-2-Phenyl hydrozono-3-oxobutyrate on the corrosion behaviour of 15 volume % 6061 Al alloy SiCp composite in 0.5 and 1 Normal hydrochloric acid media using potentio-static polarization technique. The study reveals that the Inhibition Efficiency of the compound increases with increase in concentration of the inhibitor upto a critical concentration. The results obtained indicate that Oxobutyrete is an excellent cathodic inhibitor. The adsorption of the compound on the 6061 Al alloy/Si Cp composite surface is found to obey Temkins′ and Langmuir adsorption isotherms and inhibition is governed by physisorption mechanism
