There is a need for materials of exceptional hardness in order to coat mechanical components. One way to do this is take advantage of the properties of nanostructured materials. This book delivers practical insights into a broad range of fields related to hard coatings, from their deposition and characterization up to the hardening and deformation mechanisms, allowing the interpretation of results. In addition to the above-mentioned hardness, this type of coating often must meet other stringent criteria for mechanical properties such as, excellent adhesion to the substrate and very high fracture toughness and other requirements. Their use in chemical aggressive environments at very high temperatures demand also very high oxidation/corrosion resistance and thermal stability. Thus, increasing concern is prevalent among researchers in this field concerning the development of coatings that could satisfy simultaneously all the necessary properties to guarantee successful implementation in real mechanical applications.

Finish Manufacturing Processes are those final stage processing techniques which are deployed to bring a product to readiness for marketing and putting in service. Over recent decades a number of finish manufacturing processes have been newly developed by researchers and technologists. Many of these developments have been reported and illustrated in existing literature in a piecemeal manner or in relation only to specific applications. For the first time, Comprehensive Materials Finishing, Three Volume Set integrates a wide body of this knowledge and understanding into a single, comprehensive work. Containing a mixture of review articles, case studies and research findings resulting from R & D activities in industrial and academic domains, this reference work focuses on how some finish manufacturing processes are advantageous for a broad range of technologies. These include applicability, energy and technological costs as well as practicability of implementation. The work covers a wide range of materials such as ferrous, non-ferrous and polymeric materials. There are three main distinct types of finishing processes: Surface Treatment by which the properties of the material are modified without generally changing the physical dimensions of the surface; Finish Machining Processes by which a small layer of material is removed from the surface by various machining processes to render improved surface characteristics; and Surface Coating Processes by which the surface properties are improved by adding fine layer(s) of materials with superior surface characteristics. Each of these primary finishing processes is presented in its own volume for ease of use, making Comprehensive Materials Finishing an essential reference source for researchers and professionals at all career stages in academia and industry.

Phenomena associated with the adhesion interaction of surfaces have been a critical aspect of micro- and nanosystem development and performance since the first MicroElectroMechanicalSystems(MEMS) were fabricated. These phenomena are ubiquitous in nature and are present in all systems, however MEMS devices are particularly sensitive to their effects owing to their small size and limited actuation force that can be generated. Extension of MEMS technology concepts to the nanoscale and development of NanoElectroMechanicalSystems(NEMS) will result in systems even more strongly influenced by surface forces. The book is divided into five parts as follows: Part 1: Understanding Through Continuum Theory; Part 2: Computer Simulation of Interfaces; Part 3: Adhesion and Friction Measurements; Part 4: Adhesion in Practical Applications; and Part 5: Adhesion Mitigation Strategies. This compilation constitutes the first book on this extremely important topic in the burgeoning field of MEMS/NEMS. It is obvious from the topics covered in this book that bountiful information is contained here covering understanding of surface forces and adhesion as well as novel ways to mitigate adhesion in MEMS/NEMS. This book should be of great interest to anyone engaged in the wonderful and fascinating field of MEMS/NEMS, as it captures the current R&D activity.

Surfactants are vital components in biological systems, are key ingredients in many formulated products and play an important role in many industrial processes. The property which makes surfactants so useful is their ability to stabilize complex colloidal and interfacial systems. It is not surprising therefore that many new surfactant materials are developed, many of which have novel properties. However because their potential is not fully appreciated they remain underutilized by industry. The main purpose of this book is to illustrate the utility of a range of novel surfactants, in particular those which have been found useful in specific areas and which seem to offer promise across a wider range of applications. The contributors are drawn from industry and academic research and provide a comprehensive account of the preparation, properties and applications of these specialist surfactants. Research chemists in industry and academia will find this book a concise and authoritative account of this important group of surfactants.

The spread of modern coating technology is impeded by the slow development of the special methods of evaluating their stucture and properties. Most publications consider only the technological aspects of the modern coating methods. This, combined with a lack of a well-grounded scientific analysis of the investigation results, not only thwarts the possibility for improving the coating modes, but also can compromise a clearly progressive technology. This book can be viewed as a scientific investigation combined with methodological studies. For practical reasons each of the methods is described in the following general manner including: the uses and the scientific investigation tasks; methods of sampling; testing equipment; test preparation; tests; data processing; controversial issues and conclusions. Each of the 37 methods contains a range of 1 to 8 variants. As far as we know, the book is the first publication in the field.

The analysis of surfactants presents many problems to the analyst. This book has been written by an experienced team of surfactant analysts, to give practical help in this difficult field. Readers will find the accessible text and clear description of methods, along with extensive references, an invaluable aid in their work.

Nanoscience and Nanotechnology are experiencing a rapid development in many aspects, like real-space atomic-scale imaging, atomic and molecular manipulation, nano-fabrication, etc. , which will have a profound impact not only in every field of research, but also on everyday life in the twenty-first century. The common efforts of researchers from different countries and fields of science can bring complementary expertise to solve the rising problems in order to take advantage of the nanoscale approaches in Materials Science. Nanostructured materials, i. e. materials made with atomic accuracy, show unique properties as a consequence of nanoscale size confinement, predominance of interfacial phenomena and quantum effects. Therefore, by reducing the dimensions of a structure to nanosize, many inconceivable properties will appear and may lead to different novel applications from na- electronics and nanophotonics to nanobiological systems and nanomedicine. All this requires the contribution of multidisciplinary teams of physicists, chemists, materials scientists, engineers and biologists to work together on the synthesis and processing of nanomaterials and nanostructures, und- standing the properties related to the nanoscale, the design of nano-devices as well as of new tools for the characterization of nano-structured materials. The first objective of the NATO ASI on Nanostructured Materials for Advanced Technological Applications was to assess the up-to-date achie- ments and future perspectives of application of novel nanostructured materials, focusing on the relationships material structure ? functional properties ? possible applications.

Emulsification of vegetable oil-based resins was a daunting task when the author began his research, but the subsequent technology spawned a generation of stable emulsions for waterborne coatings based on vegetable oil-based alkyd resins, oils and fatty acids. Autoxidative polymerization of emulsified alkyd resins is an innovative and original contribution to emulsion technology, because conventional emulsion-polymerization is not applicable to alkyd resins. Emulsified alkyd particles are polymerized while dispersed in stable aqueous media-an original and patented innovation. Smooth and fa- drying alkyd coatings are generated from non-polymerized emulsions and air-dried with conventional metal driers, and have met with marketing success. The pre-polymerization innovation for emulsified alkyd particles provides very fast air-drying coatings that have potential markets for interior architectural latex coatings and waterborne pressure-sensitive adhesives and inks. The author demonstrates his knowledge of chemical reaction kinetics by employing a combination of oxygen concentration, internal reactor pressure and other reactor variables to finely control the rate and degree of autoxidative polymerization. He meticulously calculates surfactant chemistry by measuring hydrophile-lipophile balance values, and solubility parameters to emulsify characterized resins. The relationship between hydrophi- lipophile values and solubility parameters is shown in explicit equations. Homogenization equipment used during the course of this research to generate emulsions is shown in detailed drawings together with concise particle size and distribution data. The author reports research spawned internationally by his research in the fields of alkyd-acrylic hybrids, polyester and oil-modified urethane resins.

The measurement and characterisation of surface topography is crucial to modern manufacturing industry. The control of areal surface structure allows a manufacturer to radically alter the functionality of a part. Examples include structuring to effect fluidics, optics, tribology, aerodynamics and biology. To control such manu-facturing methods requires measurement strategies. There is now a large range of new optical techniques on the market, or being developed in academia, that can measure areal surface topography. Each method has its strong points and limitations. The book starts with introductory chapters on optical instruments, their common language, generic features and limitations, and their calibration. Each type of modern optical instrument is described (in a common format) by an expert in the field. The book is intended for both industrial and academic scientists and engineers, and will be useful for undergraduate and postgraduate studies.

A general and introductory survey of foams, emulsions and cellular materials. Foams and emulsions are illustrations of some fundamental concepts in statistical thermodynamics, rheology, elasticity and the physics and chemistry of divided media and interfaces. They also give rise to some of the most beautiful geometrical shapes and tilings, ordered or disordered. The chapters are grouped into sections having fairly loose boundaries. Each chapter is intelligible alone, but cross referencing means that the few concepts that may not be familiar to the reader can be found in other chapters in the book. Audience: Research students, researchers and teachers in physics, physical chemistry, materials science, mechanical engineering and geometry.

The awareness and development of 'biodegradable' surfactants pre-dates current pressures by the environmental movement by nearly three decades, wherein a responsible industry mutually agreed to replace 'hard', non-biodegradable com ponents of household detergents by 'soft', biodegradable alternatives, without course to legislation. The only requirement at that time was for surfactants used in detergents to exhibit a 'primary biodegradability' in excess of 80%; this referring to the disap pearance or removal from solution of the intact surface active material as de tected by specified analytical techniques. This proved useful, as observed environmental impacts of surfactants, e.g. visible foam on rivers, are associated with the intact molecule. Test methods for 'primary biodegradability' were eventually enshrined in EU legislation for nonionic surfactants (Directive 821242/EEC, amended 73/404IEEC) and for anionic surfactants (Directive 8212431EEC, amended 73/405IEEC). No approved test methods and resultant legislation have been developed for cationic and amphoteric surfactants to date. The environmental classification of chemical substances, which of course includes surfactants, and associated risk assessment utilises a second criterion 'ready biodegradability'. This may be assessed by a number of methods which monitor oxygen uptake (BOD), carbon dioxide production or removal of dis solved organic carbon (DOC). Some surfactants which comply with the above Detergents Directive are borderline when it comes to 'ready biodegradability'."
