Tribologisch hoch beanspruchte Gleitsysteme wie Hochdruckpumpen für die Benzindirekteinspritzung besitzen ein Belastungskollektiv, das Werkstoffe mit niedrigen Reibungszahlen und geringem Verschleiß bei gleichzeitig hoher mechanischer Festigkeit erfordert. Im Rahmen dieser Arbeit wurden Sialon-Keramiken für derartige Anwendungen entwickelt und charakterisiert. Diese zeigten hervorragende mechanische und tribologische Eigenschaften und somit ein hohes Potential für diesen Einsatzbereich.

Zur gezielten Beeinflussung des Reibungsverhaltens können Wirkflächentexturierungen ein effizientes Hilfsmittel darstellen und waren daher Kern dieser Untersuchungen.Die Wirkung der kanalartigen Mikrotexturen auf tribologische Kenngrößen wie Schmierfilmdicke und Reibungszahl wurde durch Modellbildung auf relevante Texturkenngrößen zurückgeführt. Das Modell liefert einen Ansatzpunkt zur systemspezifischen Auslegung von Texturierungen als Konstruktionsdetail in ölgeschmierten Friktionssystemen.

This reference, in its second edition, contains more than 7,500 polymeric material terms, including the names of chemicals, processes, formulae, and analytical methods that are used frequently in the polymer and engineering fields. In view of the evolving partnership between physical and life sciences, this title includes an appendix of biochemical and microbiological terms (thus offering previously unpublished material, distinct from all competitors.) Each succinct entry offers a broadly accessible definition as well as cross-references to related terms. Where appropriate to enhance clarity further, the volume's definitions may also offer equations, chemical structures, and other figures. The new interactive software facilitates easy access to a large database of chemical structures (2D/3D-view), audio files for pronunciation, polymer science equations and many more.

This book provide new insights into the theoretical and applied aspects of metal electrodeposition. The theory largely focuses on the electrochemistry of metals. Details on the practice discuss the selection and use of metal coatings, the technology of deposition of metals and alloys, including individual peculiarities, properties and structure of coatings, control and investigations. This book aims to acquaint advanced students and researchers with recent advances in electrodeposition, while also being an excellent reference for the practical electrodeposition of metals and alloys.

This volume presents material science and mechanical issues of hybrid adhesive bonds which are a combination of adhesive bonding and mechanical fastening, interference or welding. The hybrid concept includes also mixed-adhesive bonding, where at least two adhesives with different mechanical properties are placed along the bondline. The idea of hybrid joints is to gather the advantages of the different techniques leaving out their problems. Some of the advantages of these joints are a higher static and fatigue strength and a higher stiffness with respect to simple joints, a two-stage failure process and improved durability. The book treats all important kinds of hybrid joints which are in use today: weld - adhesive, rivet - adhesive, clinch - adhesive, bolt - adhesive, and adhesive - adhesive. A section dedicated to threadlocking and interference-fit adhesive joints is also included. All sections are treated from a scientific point of view with modeling issues supported by simple coupons testing and a technological point of view where the idea is to present more applied results with practical cases.

During the 2010 EFORT Congress in Madrid, many interesting topics relating to tribology in total hip arthroplasty were discussed during a special day devoted entirely to the subject. So successful was the day, and such was the broad interest in the discussions, that EFORT decided that publication of all the presentations would be warmly welcomed by fellow professionals who were unable to attend. This book is the result. It includes detailed information on the different articulating materials and the wear to which they are subject. The various factors that contribute to bearing performance and control wear are thoroughly evaluated, and careful consideration is given to the technology and design solutions proposed with a view to producing low-wearing hip joints. This book will be of interest both to novices who want to learn more about the field and to experienced orthopaedic surgeons wishing to keep abreast of the latest developments.

Es wird die Herstellung und Charakterisierung von partikulären Stahl-Keramik-Verbundwerkstoffen beschrieben. Die Rohmaterialien wurden pulvermetallurgisch verarbeitet und durch sogenanntes ""Field Assisted Sintering"" (auch SPS) verdichtet. Anschließend wurde Mikrostruktur, Härtbarkeit, mechanische und tribologische Eigenschaften untersucht. Härte und Verschleißbeständigkeit konnten deutlich verbessert werden, wobei die Festigkeit und Zähigkeit mit höheren Partikelgehalten deutlich abnahm.

Hard machining is a relatively recent technology that can be defined as a machining operation, using tools with geometrically defined cutting edges, of a work piece that has hardness values typically in the 45-70HRc range. This operation always presents the challenge of selecting a cutting tool insert that facilitates high-precision machining of the component, but it presents several advantages when compared with the traditional methodology based in finish grinding operations after heat treatment of work pieces. Machining of Hard Materials aims to provide the reader with the fundamentals and recent advances in the field of hard machining of materials. All the chapters are written by international experts in this important field of research. They cover topics such as: ¢ advanced cutting tools for the machining of hard materials; ¢ the mechanics of cutting and chip formation; ¢ surface integrity; ¢ modelling and simulation; and ¢ computational methods and optimization. Machining of Hard Materials can serve as a useful reference for academics, manufacturing and materials researchers, manufacturing and mechanical engineers, and professionals in machining and related industries. It can also be used as a text for advanced undergraduate or postgraduate students studying mechanical engineering, manufacturing, or materials.
