Metallic Protective Coatings of Magnesium Metal in Ionic Liquids

    Magnesium is a reactive element, poor corrosion resistance and highly unstable, which have limited its industrial applications.One of the most effective ways to improve the corrosion resistance of Mg and its alloys is to form a coating on the surface to isolate them from the environment.This can be achieved by forming or applying some type of functional barrier layer. There are several surface coating treatment techniques,including electrochemical plating (electroplating), conversion coating,anodizing, hybrid coatings, and vapor-phase process.

Characterization of Red Apple and Pomegranate Peels Extracts as Corrosion Inhibitors for αBrass in Acidic Media

          The present thesis consists of four chapters that throws the light on studying the corrosion behavior of`α-brass in the acidic media using the potentiostatic polarization. Each chapter discusses many topics can be demonstrated as following:
1. Chapter one discusses the introduction topics about corrosion, corrosion forms, electrochemical aspects and copper alloys.  
2. Chapter two discusses the experimental procedures and techniques about characterization of the pomegranate and red apple peels and the polarization study.

Synthesis and Identification of Heterocyclic Compounds as Corrosion Inhibitors in Acidic Media

In this study, Heterocyclic  Compounds were synthesized by several steps as following:

First step: the 1-[4-(5-Bromo-pentyloxy)-phenyl]-ethanone (B1) was synthesized by treatment of    4-hydroxyacetophenon (A) with 1,5-dibromo pentane  in presence of  anhydrous potassium carbonate and acetone.
