Corrosion and its control

In practice, corrosion is an insidious process which is often difficult to recognize until deterioration is well advanced it may have the following interrelated results  

Damage to process plant, structural assemblies and other equipment. 

Risk of injury to personnel due, for example, to leakage or mechanical fractures. 

Whatever the results of corrosion, remedial work may be costly in terms of 

Chemical properties of metals and alloys (heterogeneities may — be submicroscopic microscopic, or macroscopic)

Corrosion and its control mean the corrosion process and the measures taken to control or keep in check the corrosion process. Sometimes it is also referred to as corrosion, prevention and protection. Although the terms prevention and protection appear to be synonymous, prevention means measures taken to control corrosion to a limited extent while protection means extensive or more comprehensive measures taken to control the corrosion process. In more general terms preventive measures are knowledge-based while protection involves both known and unknown factors, such as natural disasters.
