The purpose of this book is to provide engineers, designers, architects, and all those involved with the selection of construction materials some basic information concerning the causes, prevention, and control of corrosion. Corrosion is both costly and dangerous. Billions of dollars are spent annually for the replacement of corroded structures, machinery, and components. Premature failure of bridges or structures due to corrosion can also result in human injury, loss of life, and collateral damage. Taking all these factors into account, it becomes obvious why those persons involved with the design and/or maintenance of structures and equipment should have a basic understanding of the corrosion process.
This book explains the mechanisms and forms of corrosion; the methods of attack on plastic materials; and the causes of failure of protective coatings, linings, and paints. Except for Chapter 4 that deals with atmospheric corrosion, the effect of specific corrodents on a specific material of construction is not covered, although ample sources for this information will be provided. In that chapter the effects of corrodents present in the atmosphere are discussed. Information is also included to assist in the design and selection of materials of construction to avoid or keep to a minimum the effects of corrosion.




There are three primary reasons for concern about and study of corrosion: safety, economics, and conservation. Premature failure of bridges or structures due to corrosion can result in human injury or even loss of life. Failure of operating equipment can have the same disastrous results. Several years ago, the National Institute of Standards and Technology (formerly the National Bureau of Standards) estimated that the annual cost of corrosion in the United States was in the range of $9 billion to $90 billion. These figures were confirmed by various technical organizations, including the National Association of Corrosion Engineers. Included in this estimate was corrosion attributed to chemical processes:
to corrosion of highways and bridges from de-icing chemicals; to atmospheric corrosion of steel fences; to atmospheric corrosion of various outdoor structures such as buildings, bridges, towers, automobiles, and ships; and innumerable other applications exposed to the atmospheric environment. It has been further estimated that the cost of protection against atmospheric corrosion is approximately 50% of the total cost of all corrosion protection methods. These concerns and studies have been responsible for the development of new alloys and many nonmetallic materials of construction, specifically a wide range of plastic materials of the thermoset and thermoplastic varieties, as well as the development of a wide variety of coatings and linings. When selecting a material of construction for a particular application, that material must have certain physical, mechanical, and corrosion-resistant properties.
