Book Chemical Vapor Deposition of Oriented Tungsten Foils for Thermionic Cathodes

Download or read book Chemical Vapor Deposition of Oriented Tungsten Foils for Thermionic Cathodes written by L. Yang and published by . This book was released on 1983 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts under the present contract were devoted to the preparation of CVD tungsten emitters containing a variety of preferred crystallographic orientations. The work is divided into two phases. In Phase I, a CVD tungsten deposition apparatus was built and CVD tungsten samples of various preferred crystallographic orientations were prepared and characterized with respect to microstructures and nature and degree of preferred orientations. These samples were delivered to NRL for the evaluation of their electron emission properties. In Phase II, efforts were made to produce a high degree of preferred crystallographic orientations in thin CVD tungsten deposits (approx. 25 micron thickness) which are amenable to hole drilling by laser. Techniques for preparing CVD tungsten cathode structure were established and samples of oriented tungsten cathode structure were prepared for NRL evaluation.

Book Chemical Vapor Deposition of Tungsten and Tungsten Silicides for VLSI ULSI Applications

Download or read book Chemical Vapor Deposition of Tungsten and Tungsten Silicides for VLSI ULSI Applications written by John E. J. Schmitz and published by William Andrew Publishing. This book was released on 1992 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph condenses the relevant and pertinent literature on blanket and selective CVD of tungsten (W) into a single manageable volume. The book supplies the reader with the necessary background to bring up, fine tune, and successfully maintain a CVD-W process in a production set-up. Materials deposition chemistry, equipment, process technology, developments, and applications are described.

Book Study of Tungsten IV and Tungsten VI Imido Complexes

Download or read book Study of Tungsten IV and Tungsten VI Imido Complexes written by Corey B. Wilder and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of tungsten guanidinate and amidinate complexes were synthesized to serve as precursors for the metal-organic chemical vapor deposition of tungsten nitride. Compounds were characterized by 1H and 13C NMR. In addition, mass spectrometry was used for characterization as well as to give insight into precursor fragmentation tendencies. Crystallography experiments were also conducted to investigate the bonding motifs present in the series of compounds.

Book Process Development and Characterization of Chemical Vapor Deposited Tungsten for Gun Barrel Applications

Download or read book Process Development and Characterization of Chemical Vapor Deposited Tungsten for Gun Barrel Applications written by Richard A. Harlow and published by . This book was released on 1973 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 20-month program was conducted to develop improved chemical vapor deposition (CVD) processes for applying tungsten to the bores of gun barrels, and further, to characterize the physical and mechanical properties of the CVD tungsten as deposited. Conventional and high strain-rate tensile and compression tests were conducted on CVD tungsten as deposited on 4150 steel at temperatures of -65 F, ambient, and 200 F. Density, thermal expansion, and thermal conductance measurements were also made. Barrel materials of 4150 steel, CG-27, L-605, 718, and Pyromet X-15 were investigated. Based on test firings, acceptable CVD tungsten adherence was demonstrated on 4150, but the other four alloys revealed only marginal quality. Fourteen .220 Swift/MG-3 tests barrels of the five materials were fabricated and delivered to the Air Force. (Author).
