a atudy of the electrochemical behavior of copper in acid medium in presence of some amine compounds

1. Investigate the inhibition effect of some amine compounds towards the corrosion of copper in H3PO4 acid solutions using the chemical method (weight loss method).2. Determination of the rate of corrosion of copper in H3PO4 solutions in absence and presence of different concentrations of the amine compounds at 25 oC.3. Determination of the type and kind of adsorption isotherm at 25 oC.4. Finally, ordered these amine compounds according their percentage inhibition.Second:Study the phenomenon of electropolishing which is important as metallic finishing process which takes place before electroplating of metal. A great deal of work has been directed to study the mechanism of electropolishing as well as establishing the optim
