Surface Modification for Improved Propertieseful role in the service life of the material. Such surface/bulk material combinations can be considered as composites, with surfaces ranging from a naturally occurring oxide layer protecting such metals as aluminum, titanium, and stainless steel to very deliberately tailored additions of alloying e

Characterization of Surfacesces in electronics which allow the detection of signals emerging from layers of minute thickness less than 100Å. A knowledge of the compositional and geometrical features of the surface help to devise processes for improved surface performance and properties, which is the theme of this book. This di
