is a major cause of the deterioration of engineering structures, and has
an associated cost that is about 5% of the gross national product. This
implies that corrosion control is an important consideration in the design
process. The process is not only associated with large engineering structures,
but is associated with semiconductor devices and materials used to fabricate
medical implants. Biocompatibility of implants involves material stability
in the biological environment as well as the non-toxic nature of the material
and its corrosion products.
section will explore some of the fundamental reactions involved in corrosion
and strategies to minimize the corrosion process.
