Treatise on Materials Science and Technology, Volume 18: Ion Implantation is a compendium of the active areas of ion implantation in materials science and technology. Topics covered range from the basic to the applied aspects of metallurgy, chemistry, and solid-state physics. The focus is on the non-electronic applications of ion implantation in materials, with main emphasis on metals. Comprised of 11 chapters, this volume begins with an overview of ion implantation, including its characteristics and history; advantages and limitations; status of industrial applications; and equipment and costs. The discussion then turns to ion bombardment effects on material composition; the use of ion implantation in investigating alloys that consist primarily of thermodynamic equilibrium phases; and the formation of metastable phases in alloys during the implantation process. Subsequent chapters deal with the use of ion implantation to study superconductivity as well as the behavior of hydrogen in solids; the effect of ion implantation on aqueous corrosion; manufacturing applications of ion implantation; and chemical properties of ion-implanted materials. The book concludes with an analysis of the optical effects of ion implantation. This monograph will be a useful resource for practitioners and researchers in the fields of physics, metallurgy, chemistry, and materials science.
