Science Of Ceramic Interfaces

This collection of papers arose from the Proceedings of the International Workshop on Interfaces of Ceramic Materials held in Australia, 1993 and is a continuation of the previous book published under the same title. The objective of the Workshop was to discuss research progress on the chemistry of ceramic interfaces and related industrial aspects. Due to the multidisciplinary character of ceramic interfaces the book contains articles covering several areas of expertise, including ceramics, surface science, solid state electrochemistry, metallurgy and high temperature chemistry. Some technical papers are also included in this volume. Scientists and engineers working in these areas, as well as students in materials science and engineering, will find this book of particular significance.

The 17th University Conference on Ceramics, which also was the 7th LBL/MMRD International Materials Symposium, was held on the campus of the University of California at Berkeley from July 28 to August 1, 1980. It was devoted to the subject of surfaces and interfaces in ceramic and ceramic-metal systems. The program was timely and of great interest, as indicated by the large number of contributed papers, which included contributions from ten foreign countries. These proceedings are divided into the following categories dealing with the chemistry and physics of interfaces: calculations of interface/surface states, characterization of surfaces and inter faces, thermodynamics of interfaces, influence of surface and inter faces on selected ceramic processes, grain boundary structures, effects of grain boundaries on deformation and fracture, interfacial phenomena, formation of interfaces, development of adhesion, and reactions at interfaces. A number of papers deal specifically with the Si-Si02 interface, which probably has received more attention than any other because of its importance in the electronics industry. This coverage fulfills the principal objective of the symposium which was to explore and assess the current fundamental understand ing of interfaces and surfaces. A parallel objective of the symposium was fulfilled by a group of papers dealing with the correlation of interfacial characteris tics with mechanical behavior. This group includes papers dealing with the adherence of dissimilar materials at interfaces.

This proceedings offers information for those interested in the fundamental aspects of ceramic surface and interfacial phenomenon such as wetting, adhesion, chemical reactivity, and structure-property relationships, and the influence of these factors on the nature of bonding/joining of ceramic materials.

This volume provides a one-stop resource, compiling current research on ceramic coatings and interfaces. It is a collection of papers from The American Ceramic Society s 32nd International Conference on Advanced Ceramics and Composites, January 27-February 1, 2008. Papers include developments and advances in ceramic coatings for structural, environmental, and functional applications. Articles are logically organized to provide insight into various aspects of ceramic coatings and interfaces. This is a valuable, up-to-date resource for researchers in industry, government, or academia who work in ceramics engineering.

As engineering materials and structures often contain a metal or metallic alloy bonded to a ceramic, the resultant interface must be able to sustain mechanical forces without failure. They also play an important role in oxidation or reduction of materials. The workshop on 'Bonding, Structure and Mechanical Properties of Metal/Ceramic Interfaces' was held in January 1989 within the Acta/Scripta Metallurgica conference series. It drew together an international collection of 70 scientists who discussed a wide range of issues related to metal-ceramic interfaces. The sessions were divided into 7 categories: structure and bonding, chemistry at interfaces, formation of interfaces, structure of interfaces, thermodynamics/atomistics of interface fracture, mechanics of interface cracks, and fracture resistance of bimaterial interfaces. Within these headings attention was paid to grain boundaries, the influence of chemical processes on the behaviour of interfaces, diffusion bonding, characterization of fracture, and crack propagation by fatigue and by stress corrosion. The book presents a useful reference source for materials scientists, physicists, chemists, and mechanical engineers who are concerned with the roles and properties of interfaces.

The objective of the present publication is to discuss various aspects relevant to the interface of ceramics from a number of standpoints that should as distinct as possible. The aim has been reached by presenting the contributions of a wide spectrum of specialists. This approach enables the reader to grasp the present level of knowledge and to understand the problems in research of various fields relevant to ceramic interfaces. Further, it facilitates a charting of the direction of future research in these fields which are much too complex to be covered by a single scientific discipline. The majority of papers have been prepared in review type so that researchers of other fields can easily gain very detailed understanding on the interfaces of ceramics. The topics covered reach from basic science to the frontier of advanced technologies.
