THE INHIBITIVE EFFECT OF ALANINE ON CORROSION OF ALUMINIUM IN 0.5 M HCL SOLUTION USING THE WEIGHT LOSS TECHNIQUE

BACKGROUND OF STUDY: Corrosion is defined as a natural process, which converts refined metal to their more stable oxide. It is the gradual destruction or degradation of materials (usually metals) by chemical reaction with their environment which are most likely inevitable. Corrosion is a natural and costly process of destruction like earthquakes, tornados, floods and vocanic eruptions, with one major difference. Whereas we can be only a silent spectator to the above processes of destruction, corrosion can be prevented or at least be controlled.

Despite different definitions, it can be observed that corrosion is basically the result of interaction between materials and their environment. Up to the 1960’s, the term corrosion was restricted only to the metals and their alloys and it did not incorporate ceramics, polymers, composites and semiconductors in its regime. The term corrosion now encompasses all types of natural and man – made materials including biomaterials and nanomaterials, and it is not confined to metals and alloys alone. The scope of corrosion is consistent with the revolutionary changes in materials development witnessed in recent years.
