ABSTRACT
Corrosion is an electrochemical process where by most metals react with oxygen and moisture in the surrounding air to form oxides. As a result of such reactions, the metals gradually deteriorate Corrosion includes the dissolution of ceramic materials and can be refer to as discoloration of and weakening of polymers by the sun ultraviolet light. It is also observed that we have different or various forms of corrosion such as pitting corrosion cervice corrosion, galvanic corrosion, stress corrosion etc. The identification of these forms of corrosion is an important steps towards resolving the problems associated with corrosions. There are various techniques used for monitoring corrosion but not single techniques can provide answers to all corrosion problems. But a good result could be gotten by combination of different techniques. Aims and objectives (i) to investigate corrosion of aluminium in alcohol (ethyl alcohol or ethanol) medium (ii) to determine the inhibitive effect of hexamine compound containing nitrogen on alchhol corrosion of aluminium. Gravimetric studies of corrosion of aluminum in the presence of an organic inhibitor. An organic inhibitor is a chemical compound that reduces the corrosion rate of the metals and alloys when it is added in small amount or concentration into the corrosive media or environment of the metallic material. It reduces the rate of corrosion by being absorbed on the metal surfaces.The inhibitive effect of hexamine on corrosion rate of aluminum in 99%, 98%, 97%, 96%, 95% of ethyl alcohol solution was studied by gravimetric technique. It was found that this organic inhibitor behavior was more pronounced at the highest concentration of the medium and inhibits better at a lower concentration. The inhibitive efficiency ranges from 50.00%-71.43%.
