Fundamentals of Corrosion
1.4 Nonmetallic Materials
Metallic materials do not stand alone in their susceptibility to corrosion.
Other materials such as plastics, concrete, paint, coatings, and linings are
also subject to corrosion. In the case of paints, coatings, and linings, failure may result from the corrosion of the substrate material due to improper
application or the physical properties of the protective material.
In any case, corrosion is at the root of the failure.
1.5 Summary
When all the above factors are considered, it becomes obvious why the
potential problem of corrosion should be considered during the early
design stage of any project and why it is necessary to constantly monitor
the integrity of structures, bridges, machinery, and equipment to prevent
premature failure.
To cope with the potential problems of corrosion, it is necessary to
understand:
1. Mechanisms of corrosion
2. Forms of metallic corrosion
3. Corrosive attack on nonmetallic materials
4. Corrosion-resistance properties of various materials
5. Proper fabrication and installation techniques
6. Methods to prevent or control corrosion
7. Corrosion testing techniques
8. Corrosion monitoring techniques
It is the intention of this book to deal with items 1, 2, 3, and 6. Ample references for additional reading are provided to cover the remaining items. The
subject matter covered in the book includes the basics to the understanding
of corrosion and how to eliminate and/or control it.
