History of corrosion mitigation is the saga of the deve-lopment of engineering equipment and systems. Corrosion began when mankind embarked on the exploitation of res-ources and with that also started the process of miti-gating corrosion failures. Initially engineers and des-igners learnt to protect surfaces with paints and coats. Then they went for selecting similar materials and prov-iding proper drainage to avoid corrosion. Going for butt joints rather than lap joints and using drip skirts were employed later for protection against moisture and corro-sion. Resilient sealants to exclude ,moisture from pote- ntial crevices and cathodic protection are some of the 'grandma " remedies of engineering. A voiding turbulence, using non-metallic materials, providing redundan,' and spare systems and the like have been few of the defensive strategies from the past. While talking about corrosion damage, it is natural to think first of all about the destruction of the material of construction and machinery. However, corrosion damage also includes the deleterious effects caused to the surro-undings, such as undesirable discolouration or alteration in the taste ofproducis e.g., foodstuffs, that are tainted by corrosion products toxicity caused to the environment because of unwanted expulsion ofgases and toxic materials. The concept ofcorroslon has thus widened to include such phenomena and encompasses the entire spectrum of effects in virtually every industry, and society where materials are processed and used.
