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.
