Near Surface Modification: New Techniques and Applications in Materials Science

摘要

This report reviews several new materials processing techniques or new applications of some existing techniques which have lead to new materials modifications. It is intended to acquaint ORNL researchers with the capabilities of these techniques and the facilities which exist at ORNL. Section I contains the rationale and motivation for this report and discusses the extent to which the near-surface regions of materials can be modified utilizing the various techniques. The near-surface modification techniques themselves are described in Section II. The more established techniques considered are physical and chemical vapor deposition and liquid quenching. Particular emphasis is placed on the newer techniques of ion implantation doping, pulsed laser annealing and ion-beam and pulsed-laser mixing. Four areas were singled out for consideration in Section III and the usefulness of these near-surface modification techniques in these areas were assessed. (ERA citation 07:057371)
