Book Description
One of the increasingly important requirements for high technology materials is that they possess near-surface properties different to their bulk properties. Specific surface properties are generally achieved through the use of these films or coatings or by modifying the structure or composition of the near surface. This two-volume work contains 157 papers covering a wide range of topics involving films, coatings, and modified surfaces. All aspects of the development of deposition technologies are addressed including basic research, applied research, applications development and full scale industrial production. The work will be of interest to materials scientists, physicists, electronic, chemical and mechanical engineers, and chemists.

Book Description
We present results of a study of hemispherical pins of manganese-zinc ferrite sliding against rigid disks composed of thin films of a sputtered cobalt-nickel-platinum alloy and carbon, with perfluoropolyether as the topical lubricant. The contact life, as marked by the total distance slid to the point at which the coefficient of friction increases rapidly over the steady state value, is much longer in air with 50 percent relative humidity than in dry air or vacuum. The wear debris generated in humid air is much finer and is enriched with cobalt on its surface. In dry air and vacuum, the debris is substantially larger than one micron and tends to be enriched with nickel on its surface. We present a hypothesis which explains the wear mechanisms in various operating environments.

Book Description
Understanding the composition and structure of a surface is essential in understanding its frictional (Tribological) properties. This volume in the Materials Characterization series will focus on surface characterization, including roughness, hardness, coating thickness and bond strength. Advanced characterization methods are also covered for applications in magnetic recording media, rolling contact bearings and other high-tech systems. -- Reviews major physical principles of tribology, including adhesion, friction, abrasion and surface boundary conditions -- Special section on surface characterization of magnetic recording surfaces -- Concise summaries of major characterization technologies for tribological materials, including SEM, Energy-Dispersive X-Ray Spectroscopy, Fourier Transform Infrared Spectroscopy and Static Secondary Ion Mass Spectroscopy

Book Description
Recent research has led to a deeper understanding of the nature and consequences of interactions between materials on an atomic scale. The results have resonated throughout the field of tribology. For example, new applications require detailed understanding of the tribological process on macro- and microscales and new knowledge guides the rational
