Paulette has over twenty years experience as a research scientist at
a prominent National Laboratory in the United States. Her studies
include both fundamental and engineering aspects of corrosion
processes. She has authored over 50 publications and presentations
and provided short courses in the field. She maintains a current
awareness and association with leading researchers and new
developments in Corrosion Science and its application to materials
of decay underlie the unremitting deterioration of materials and
structures (corrosion) supporting the foundations, activities, and
growth of industrialized nations. Increasingly we become critically
aware that these processes also pose a significant threat to human
safety and life. Recent studies have shown that costs related to
corrosion have more than tripled in the last twenty-five years, and
for most industrialized nations make up 3.5-4.5% of the gross
national product. Given this situation the study of Corrosion
Science and Engineering for the purposes of implementing corrosion
control in existing and new structures is an important area of
concern for materials engineers supporting national interests.
are complex electrochemical systems, and because they are keenly
material (composition) and environmentally dependent do not give way
to generalized approaches for manipulation and control. To apply
functional methods aimed at preventing, moderating, and diminishing
these processes, it would be necessary to have an understanding of
both fundamental electrochemical principles as well as the
principles supporting sound engineering practices and design. It is
in this combined domain that Dr. Ahmadís textbook fills a requisite
niche as a complete and comprehensive course text, heretofore
unavailable under one cover.
In the first three
chapters of the text Dr. Ahmad discusses the basic concepts and
fundamental electrochemical aspects of reactions underlying
materials decay. This material is discussed with clear, concise,
and thorough development of topical areas, and is supported by
numerous references to respected literature in electrochemistry.
The diagrams and charts chosen to illustrate the text are to be
commended for clarity and conciseness. A glossary of terms is
provided for each chapter, providing ready reference material. Many
illustrative problems and solutions provide excellent pedagogical
examples emphasizing core computational methods for each topic.
Solutions to end of chapter questions are available from an on-line
The remainder of
the book concerns the more practical, engineering aspects of
corrosion, including explanations of the various types of corrosion
observed (uniform, galvanic, crevice, pitting, stress corrosion
etc.) and comprehensive discussions of various methods that can be
applied for corrosion control (cathodic protection, inhibition,
coatings, corrosion control by design, materials selection,
atmospheric corrosion, boiler corrosion, and concrete corrosion).
Dr. Ahmad supports these discussions through numerous references to
seminal literature by researchers and practitioners in the field.
Of particular value are the Case Histories presented in Chapter 4
providing assessments, analysis, and recommended methods of
corrosion prevention applied to actual failures.
writing this book, Dr Ahmad has undertaken a formidable effort to
unify two important aspects of corrosion, and in so doing draws
informed attention to methods for its prevention and control. Based
on his experience, unquestionable knowledge, and fortitude he has
accomplished his task with great success. This book is likely to be
appreciated as a comprehensive text for university level courses in
the field, and as a valuable source of catalogued information for
scientists and engineers addressing a problem recognized to present
a considerable drain on the resources of all nations and
