Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2004-01-08 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Zusammenfassung: Synthetische Diamanten sind in Industrie und Wissenschaft sehr attraktiv, schaffen sie doch den Kompromiss zwischen einzigartigen Materialeigenschaften und geringen Anschaffungskosten. Mit der Verfeinerung von geeigneten CVD-Methoden und der intensiven Entwicklung von Reaktoren und Anlagen konnten die Herstellungskosten weiter gesenkt und vor allem enorme Fortschritte bei den möglichen Anwendungen und Abmessungen erzielt werden. Diese Diplomarbeit beschäftigt sich mit dem Wiederaufbau und der Integration einer unbekannten industriellen 915MHz MCPR-Anlage (microwave cavity plasma reactor), für die Herstellung von CVD-Diamanten. Dabei wird umfangreich über den Stand der Technik bei relevanten CVD-Reaktoren, Anwendungsmöglichkeiten, Synthese und Materialeigenschaften von synthetischen Diamanten eingegangen. Weiterhin wird der Aufbau und die Wirkungsweise der MCPR-Reaktoranlage beschrieben. Neben der Analyse der Ausgangsbedingungen wird auf die Umsetzung der Teilprobleme wie den Wiederaufbau des Mikrowellensystems, Vakuumanlage, Prozessgassystem und das Wasserkühlsystem eingegangen, wobei spezifische Probleme (Design, Funktion, Fehler, notwendige Änderungen) analysiert und Lösungen besprochen werden. Dabei werden Dimensionierungen von Kühlleistungen, Gasbedarfe (Prozessgase) und Einstellungen bei unbekannten Systemeigenschaften beschrieben. Weiterhin werden Dimensionierung und Auswahl von einem Kühlaggregat und Gaskühlströmen, die Konstruktion und Dimensionierung einer Hebevorrichtung und Kammergrößenskala und adäquate Systemparameterwahl erläutert, wobei auf jeweilige (un-) bekannte Randbedingungen eingegangen werden. Mit der Entscheidung von geeigneten Methoden (Helium-Leck-Test, Mikrowellenstrahlung u.a.) wurden die Teilsysteme auf Funktion und Sicherheit überprüft. Mit geeigneten Berechnungen konnten notwendige Reinheiten im Vakuumbereich (Leckratenbeurteilung, Prozessgaswechsel) erwiesen werden. Abschließend werden Funktionstests und Auswirkungen auf den gewählten Aufbau der Anlage beschrieben und Ausblicke für weitere Modifikationen und Verbesserungen gemacht. Die Arbeit zeigt mit 29 Abbildungen, 10 Tabellen und 24 Anlagen (Skizzen, Tabellen, u.a.) unterschiedliche Problemlösungen beim Wiederaufbau der Reaktoranlage.

Available in PDF, EPUB and Kindle. Book excerpt: This authoritative reference presents a comprehensive review of the evolution of plasma science and technology fundamentals over the past five decades. One of this field’s principal challenges has been its multidisciplinary nature requiring coverage of fundamental plasma physics in plasma generation, transport phenomena under high-temperature conditions, involving momentum, heat and mass transfer, and high-temperature reaction kinetics, as well as fundamentals of material science under extreme conditions. The book is structured in five distinct parts, which are presented in a reader-friendly format allowing for detailed coverage of the science base and engineering aspects of the technology including plasma generation, mathematical modeling, diagnostics, and industrial applications of thermal plasma technology. This book is an essential resource for practicing engineers, research scientists, and graduate students working in the field.

Download or read book Advanced Techniques for Surface Engineering written by W. Gissler and published by Springer Science & Business Media. This book was released on 1992-10-31 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hardest requirements on a material are in general imposed at the surface: it has to be wear resistant for tools and bearings; corrosion resistant for turbine blades; antireflecting for solar cells; and it must combine several of these properties in other applications. `Surface engineering' is the general term that incorporates all the techniques by which a surface modification can be accomplished. These techniques include both the more traditional methods, such as nitriding, boriding and carburizing, and the newer ones, such as ion implantation, laser beam melting and, in particular, coating. This book comprises and compares in a unique way all these techniques of surface engineering. It is a compilation of lectures which were held by renowned scientists and engineers in the frame of the well known `EuroCourses' of the Joint Research Centre of the Commission of the European Communities. The book is principally addressed to material and surface scientists, physicists and chemists, engineers and technicians of industries and institutes where surface engineering problems arise.

Download or read book Introduction to Surface Engineering written by P. A. Dearnley and published by Cambridge University Press. This book was released on 2017-01-16 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: This highly illustrated reference work covers the three principal types of surface technologies that best protect engineering devices and products: diffusion technologies, deposition technologies, and other less commonly acknowledged surface engineering (SE) techniques. Various applications are noted throughout the text and additionally whole chapters are devoted to specific SE applications across the automotive, gas turbine engine (GTE), metal machining, and biomedical implant sectors. Along with the benefits of SE, this volume also critically examines SE's limitations. Materials degradation pathways - those which can and those which cannot be mitigated by SE - are rigorously explained. Written from a scientific, materials engineering perspective, this concise text is supported by high-quality images and photo-micrographs which show how surfaces can be engineered to overcome the limits of conventionally produced materials, even in complex or hostile operating environments. This book is a useful resource for undergraduate and postgraduate students as well as professional engineers.

Download or read book Handbook of Carbon Graphite Diamonds and Fullerenes written by Hugh O. Pierson and published by William Andrew. This book was released on 2012-12-02 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a review of the science and technology of the element carbon and its allotropes: graphite, diamond and the fullerenes. This field has expanded greatly in the last three decades stimulated by many major discoveries such as carbon fibers, low-pressure diamond, and the fullerenes. The need for such a book has been felt for some time. These carbon materials are very different in structure and properties. Some are very old (charcoal), others brand new (the fullerenes). They have different applications and markets and are produced by different segments of the industry.Few studies are available that attempt to review the entire field of carbon as a whole discipline. Moreover these studies were written several decades ago and a generally outdated since the development of the technology is moving very rapidly and scope of applications is constantly expanding and reaching into new fields such as aerospace, automotive, semiconductors, optics, and electronics. In this book the author provides a valuable, up-to-date account of both the newer and traditional forms of carbon, both naturally occurring and man-made. This volume will be a valuable resource for both specialists in, and occasional users of carbon materials.
