High Pressure Surface Science and Engineering

In many instances of mechanical interaction between two materials, the physical contact affects only the outermost surface layer, with little discernible influence on the bulk of the material. The resultant high pressures in these localised regimes can induce surface structural changes such as deformation, phase transformation and amorphization. The understanding of these physical phenomena is critical in the study of common 'contact loading' processes such as scratching, grinding, milling, polishing, indentation testing, wear, friction and erosion. This volume, the first to cover this relatively new field of research, brings together contributions from leading experts in their respective fields, and covers experimental measurement techniques, simulation of pressure induced phase transformations, amorphization and tribology. Three chapters are devoted to surface processes in separate classes of materials; namely semiconductors, psuedocrystals and ceramics.
