Abstract

The effects of diphenyl thiourea, phenyl thiourea and N,N'-diethyl thiourea on the corrosion of 1060 aluminium in varying concentration of (0.1N and 0.5N) trichloroacetic acid at 30°C are investigated by weight loss method in conjunction to the concentration of corroding media, period of immersion of Aluminium alloy grade 1060 at the temperature 30°C with respect to the concentration of inhibitor and activation energy and adsorption isotherms are plotted to elucidate the mechanism of adsorption of inhibitor on surface of alloy in that support corrosion potential and polarization behaviour is also observed.

Keywords

Abstract

Aluminium and its alloys are light weight and corrosion resistant material and vitally preferred as materials of construction in many chemical and engineering fields. Nitrogen-containing organic compounds, such as amines and diamine derivatives on the corrosion for many metals in acidic solutions offer good protection of metallic materials. In the present investigation of corrosion inhibition of aluminium alloys of grade 1060, 1100 and 3003 in trichloroacetic acid are analysed by using conductivity and potentiostatic polarization in different inhibitors of diamine such as ethyl amino ethylamine, di-methyl amino ethylamine, 1:3 di-amino propane, tetra methyl ethylene diamine. Cathodic and anodic polarization curves are showing di-amines are acting as mixed inhibitors in the case of alloy of 3003 grade.

Keywords
