Download or read book Use of Intense Ion Beams for Surface Modification and Creation of New Materials written by and published by . This book was released on 2002 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have conducted surface treatment and alloying experiments with Al, Fe, and Ti-based metals on the RHEPP-1 accelerator (0.8 MV, 20 W, 80 ns FHWM, up to 1 Hz repetition rate) at Sandia National Laboratories. Ions are generated by the MAP gas-breakdown active anode, which can yield a number of different beam species including H, N, and C, depending upon the injected gas. Beams of intense pulsed high-power ion beams have been used to produce surface modification by changes in microstructure caused by rapid heating and cooling of the surface. Increase of beam power leads to ablation of a target surface, and redeposition of ablated material onto a separate substrate. Experiments are described in which ion beams are used in an attempt to increase high-voltage breakdown of a treated surface. Surface alloying of coated Pt and Hf layers is also described. This mixing of a previously deposited thin-film layer into a Ti-alloy substrate leads to significantly enhanced surface wear durability, compared to either untreated Ti-alloy alone, or the Ti alloy alone treated with the ion beam. Thin-film layers have been produced from a number of target materials. Films of fine-grain Pt and Er are described, and are compared to conventionally formed films. First attempts to form high-dielectric constant BaTiO3 are described.

Available in PDF, EPUB and Kindle. Book excerpt: Final report presents review of the experimental data obtained during the first and the second year of the 2-years research effort on Application of Microsecond Plasma Opening Switch (MPOS) Technology for Materials Surface Modification. Following second year programmatic plan, formulated in the conclusion of the 1-st year report we focused our effort on study of aluminum alloys modification (Al2024, 6061, 7075), including enhancement of their corrosion resistance, testing feasibility of treatment of non-planar surfaces, testing new technology of composite film formation (TiAl) and improvement of aluminum alloys bulk fatigue properties. The ion beam parameters used are 250 keV energy, and current and energy densities of 150 A/sq cm and 2.2 J/sq cm, respectively. Characterization of the treated samples showed structural changes to a depth of about +1 micron. We demonstrated factor of 3 enhancement of corrosion resistance for the treated Al alloys samples, as measured by their mass loss. EDAX and Auger analysis of irradiated Al samples with pre-deposited thin Ti films indicate that mixing due to ion beam irradiation occurs to a depth of up to 1 micron. The systematic study on the bulk tensile and fatigue properties of the MPOS treated Al2024, Al7075 alloy samples were carried out both in air and in corrosive media. The measurements indicate no deterioration of the fatigue life time in the air for the MFOS treated samples, compared with non-treated. In the same time significant enhancement of fatigue life time for the treated 7075 alloy in corrosive media (1.5 times higher in fatigue limit) was registered. For the 2024 alloy the enhancement of fatigue lifetime was detectable only for higher stresses.

Download or read book Metal Catalysed Reactions of Hydrocarbons written by Geoffrey C. Bond and published by Springer Science & Business Media. This book was released on 2006-10-03 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book, drawing on the author’s lifetime experience, critically evaluates the extensive literature on the field of Metal-Catalysed Reactions of Hydrocarbons. Emphasis is placed on reaction mechanisms involving hydrogenation, hydrogenolysis, skeletal and positional isomerisation, and exchange reactions. The motivation for fundamental research in heterogeneous catalysis is to identify the physicochemical characteristics of active centres for the reaction being studied, to learn how these may be modified or manipulated to improve the desired behavior of the catalyst, and to recognize and control those aspects of the catalyst's structure that limit its overall performance. By restricting the subject of the book to hydrocarbons, Bond has progressively developed the subject matter to include areas of importance both to researchers and to those working in the industry.

This book was released on 2013-11-21 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Present-day scienceand technology have become increasingly based on studies and applications of thin films. This is especiallytrue of solid-state physics, semiconduc tor electronics, integrated optics, computer science, and the like. In these fields, it is necessary to use filmswith an ordered structure, especiallysingle-crystallinefilms, because physical phenomena and effects in such films are most reproducible. Also, active parts of semiconductor and other devices and circuits are created, as a rule, in single-crystal bodies. To date, single-crystallinefilms have been mainly epitaxial (or heteroepitaxial); i.e., they have been grown on a single-crystalline substrate, and principal trends, e.g., in the evolution of integrated circuits (lCs), have been based on continuing reduction in feature size and increase in the number of components per chip. However, as the size decreases into the submicrometer range, technological and physical limitations in integrated electronics become more and more severe. It is generally believed that a feature size of about 0.1um will have a crucial character. In other words, the present two-dimensional ICs are anticipated to reach their limit of minimization in the near future, and it is realized that further increase of packing density and/or functions might depend on three-dimensional integration. To solve the problem, techniques for preparation of single-crystalline films on arbitrary (including amorphous) substrates are essential.

Available in PDF, EPUB and Kindle. Book excerpt: to the Fundamental and Applied Catalysis Series Catalysis is important academically and industrially. It plays an essential role in the manufacture of a wide range of products, from gasoline and plastics to fertilizers and herbicides, which would otherwise be unobtainable or prohibitively expensive. There are few chemical-or oil-based material items in modem society that do not depend in some way on a catalytic stage in their manufacture. Apart from manu facturing processes, catalysis is finding other important and ever-increasing uses; for example, successful applications of catalysis in the control of pollution and its use in environmental control are certain to increase in the future. The commercial importance of catalysis and the diverse intellectual challenges of catalytic phenomena have stimulated study by a broad spectrum of scientists, including chemists, physicists, chemical engineers, and material scientists. Increas ing research activity over the years has brought deeper levels of understanding, and these have been associated with a continually growing amount of published material. As recently as sixty years ago, Rideal and Taylor could still treat the subject comprehensively in a single volume, but by the 1950s Emmett required six volumes, and no conventional multivolume text could now cover the whole of catalysis in any depth. In view of this situation, we felt there was a need for a collection of monographs, each one of which would deal at an advanced level with a selected topic, so as to build a catalysis reference library.
