ABSTRACT
Engineering materials, to varying degrees, are susceptible to degradation as a result of interaction with the environment in which they serve. Such degradation can be classified into three main categories:
1. Corrosion and oxidation 2. Wear 3. Radiation damage
Corrosion may be defined as the unintended destructive chemical or electrochemical reaction of a material with its environment. Metallic, polymeric, and ceramic materials are susceptible to attack from different environments, and although the corrosion of metals is electrochemical in nature, the corrosion of other materials usually involves chemical reaction.
