Abstract

The corrosion inhibition of Al6061-SiCp composite in the presence of 0.5 M HCl solution containing propanoyl(1Z)-N-(2-hydoxyphenyl)-2-oxopropanehydrazonoate (PHOH) has been investigated using potentiostatic polarization techniques and weight loss method. PHOH behaves like a cathodic inhibitor for Al6061-SiCp composite in hydrochloric acid medium. The effect of concentration of PHOH and temperature of the acid medium on the inhibition efficiency was investigated. The adsorption of the inhibitor on the composite surface is found to obey Temkins’ adsorption isotherm.
