Studies on The Effect of Some Inhibitors on The Corrosion Behaviour of Alumonium and Zinc in Some Aqueous Solutions

Abstract

Studies of electrochemistry of metals are very important fields for scientific and industrial work. The present work includes detailed studies on the corrosion inhibition of zinc and aluminium in 1.0 M of sulphuric and hydrochloric acid by some ethoxylated fatty acids [ OL(E0)20 , OL(E0)40 and OL(E0)80] due to the increased industrial applications of these materials. Two techniques were used in these studies i) Chemical (weight loss) technique ii) Electrochemical (potentiodynamic polarization) technique. The present work consists of numerous chapters:- 1) Chapter (I) gives a general introduction on the corrosion studies, and gives also a literatures survey on the corrosion inhibition of Zn and Al in aqueous media. 2) Chapter (II) includes the experimental part. This includes preparation of the various solutions, electrodes and methods for testing corrosion. 3) Chapter (III) includes the results and discussion of the corrosion inhibition of Zn and Al in the two acid solutions.
