Available in PDF, EPUB and Kindle. Book excerpt: Although ceramics have been known to mankind literally for millennia, research has never ceased. Apart from the classic uses as a bulk material in pottery, construction, and decoration, the latter half of the twentieth century saw an explosive growth of application fields, such as electrical and thermal insulators, wear-resistant bearings, surface coatings, lightweight armour, or aerospace materials. In addition to plain, hard solids, modern ceramics come in many new guises such as fabrics, ultrathin films, microstructures and hybrid composites. Built on the solid foundations laid down by the 20-volume series Materials Science and Technology, Ceramics Science and Technology picks out this exciting material class and illuminates it from all sides. Materials scientists, engineers, chemists, biochemists, physicists and medical researchers alike will find this work a treasure trove for a wide range of ceramics knowledge from theory and fundamentals to practical approaches and problem solutions.

Available in PDF, EPUB and Kindle. Book excerpt: Ion beam enhanced deposition (IBED) has been used to deposit hard, adherent thin films of boron nitride with a significant cubic crystal structure present. A number of analytical techniques have been used to characterize these coatings including X-ray photoelectron spectroscopy (XPS); X-ray diffraction (XRD); transmission electron microscopy (TEM); Raman spectroscopy; nuclear radiation analysis (NRA); Rutherford Backscattering spectroscopy (RBS); and IR spectroscopy. Friction and wear behavior of these coatings was also conducted. The IBED-i-BN thin films generally exhibit a high microhardness and good adhesion to the silicon and 304 stainless steel substrates. All films (except one) had the hyperstoichiometric boron concentration. The ration Boron/Nitride approached the theoretical value at the highest current densities of the nitrogen beam. Many of the i-BN coatings exhibited low friction against 440 C stainless steel and Silicon nitride counterfaces. Friction seems to increase with increasing B/N ratios. There is a strong demand for diamond-like coatings of boron nitride (BN) in a large number of tribological applications including cryogenic bearings and adiabatic engines. Commercial use of BN coatings has previously been impeded by sample to sample reproducibility problems which have been overcome by the innovative Spire process using ion beam enhanced deposition (IBED).

Download or read book Comparison of the Optical Properties of Some High Index Oxide Films Prepared by Ion Beam Sputter Deposition with Those of Electron Beam Evaporated Films written by CK. Carniglia and published by . This book was released on 1988 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: A typical thin film of a high-index oxide coating material deposited by electron-beam (E-beam) evaporation has a refractive index lower than the bulk value for the material. This indicates that the film is porous, having a density less than the bulk density. In addition, such films are often inhomogeneous, having a higher refractive index near the substrate surface. Thin films of the same materials deposited by ion beam sputter deposition (IBD) techniques tend to have higher and more uniform refractive indices, indicating that IBD films are denser and more homogeneous. We have measured the index of refraction n, the extinction coefficient k and the degree of inhomogeneity of several high-index oxide materials deposited by IBD and by standard E-beam evaporation. The materials investigated were the oxides of zirconium, tantalum, hafnium, niobium and aluminum. In all cases, the IBD films were found to have higher refractive indices than their evaporated counterparts. The IBD films, in general, exhibited an inhomogeneity which was the reverse of the inhomogeneity found in the E-beam films. This indicates a difference in the nucleation and growth of the films. Tantala films show an absorption band in the visible spectral region resulting from electron trapping sites. Thus, this material is probably not suitable for coatings for visible and UV laser systems.
