Mechanism Of The Inhibition Afforded By Some Hydrazone Oxime Derivatives Towards Aluminium In 2m Naoh Solution
MetadataShow full item record
The effect of some hydrazone oxime derivatives on the corrosion of aluminium in 2M NaOH solution was studied by polarization and weight-loss techniques. Polarization data indicated that all inhibitors tested were of a mixed type, and appeared to function through adsorption following the Temkin adsorption isotherm. The results showed that addition of Ba2* ions enhanced inhibition action by being chemisorbed on aluminium surface. The effect of temperature on the rate of corrosion with and without inhibitors was studied using weight-loss measurements. Some thermodynamic functions were also computed.
