Corrosion of iron materials is caused by various environmental factors like different gaseous materials humidity required oxygen for oxidation. Metal is deteriorated and form rust is the form of corrosion product. Most of electronic assemblies are packed in wooden boxes which produced acidic and formic acidvapour which increased rate of corrosion product. Humid atmosphere that causes rusting. It may be brown or black depends on oxygen supply in closed boxes .If the materials are wrapped with vci soaked paper it can be protected by the vapours of anthraquinone, m-dinitrobenzene, alanine thio urea and some other related amino acids. Keywords: Amino acids, wrapped paper, ferrous metal, Alanine,
I.INTRODUCTUION Corrosion is increases in area near the sea shore. It is mainly electrochemical process promoted by different type processes differential aeration such as accumulation of dirt, sand ,scale and other contamination because this part of metal is poorly oxygenated ,hence anodic where corrosion taking place., the area becomes lesser accessible to air and more corrosion leading to the formation of deep cavity or localized pitting in the metal. Some time partial cover of metal by block of wood and piece of glass these ara working as screen part of metal from oxygen access. As a consequence, differential aeration and corrosion occurs It can be some time prevented by passivation by which a metal or alloys show high corrosion resistance due to formation of high protective, very thin film (about0.0004 mm thick) and quite invisible surface film but it can take place in different environment.Composite material means combination of more than one material with various properties. The properties of the composite are different from earlier individual materials. Within the composite [1] it is still feasible to easily tell the isolate materials [2] apart. The materials which are used to produce composite do not tend to blend or absorb each other. Man-made composite materials are available and also they exist in nature [3,4]. Fiberglass was the first modern composite and was developed in the late 1940s and is still the most common composite [5]. It fulfills about 65 percent of the demands of all the composites produced today and is used for surfboards, boat hulls, sporting goods, car bodies, swimming pool linings, and building panels. Peoples have been using composite materials for thousands of years [6], for example, mud bricks. the materials which are made up of composite .in uncorroded and metal in builts with composites can be corroded The concept of total corrosion control should be introduced in which corrosion control is more a daily activity at all stages of production than merely an afterthought. Good corrosion control. An inhibitor is a chemical substances that ,When added in small concentration to an environment, effectively decreases the corrosion rate organic inhibitors,including slashing compounds and pickling inhibitors, and vapour phase inhibitors The practice of corrosion inhibitors are greatly influen...
