This book is a toolbox for identifying and addressing tribocorrosion situations from an engineering point of view. It is an accessible and introductory guideline to the emerging and interdisciplinary field of tribocorrosion covering the main concepts of tribology and corrosion. It describes specific tribocorrosion concepts, models and experimental techniques as well as their application to practical situations in which mechanical and chemical phenomena act simultaneously.

Tribocorrosion causes the degradation or alteration of materials through the combined action of corrosion and wear. It limits the performance and life-time of installations, machines and devices with moving parts, and controls certain manufacturing processes such as chemical–mechanical polishing. The effects of tribocorrosion are most pronounced on passive metals which owe their corrosion resistance to a thin protecting oxide film. Most corrosion-resistant engineering alloys belong to this category. This book provides an introduction to the developing field of tribocorrosion and an overview of the latest research. Part one reviews basic notions of corrosion and tribology, before presenting the most recent results on the growth and structure of passive oxide films. Tribocorrosion mechanisms under fretting, sliding and erosion conditions, respectively, are then discussed. Part two focuses on methods for measuring and preventing tribocorrosion. It includes chapters on electrochemical techniques, the design of tribocorrosion test equipment, data evaluation and the optimisation of materials’ properties for tribocorrosion systems. Part three presents a selection of tribocorrosion problems in engineering and medicine. Three chapters address the tribocorrosion of medical implants including test methods and clinical implications. Other chapters examine tribocorrosion issues in nuclear power plants, marine environments, automotive cooling circuits, elevated-temperature metal working and chemical–mechanical polishing. With its distinguished editors and international team of expert contributors Tribocorrosion of passive metals and coatings is an invaluable reference tool for engineers and researchers in industry and academia confronted with tribocorrosion problems. Comprehensively reviews current research on the tribocorrosion of passive metals and coatings, with particular reference to the design of tribocorrosion test equipment, data evaluation and the optimisation of materials’ properties for tribocorrosion systems Chapters discuss tribocorrosion mechanisms under fretting, sliding and erosion conditions before focussing on methods for measuring and preventing tribocorrosion Includes a comprehensive selection of tribocorrosion problems in engineering and medicine, such as the tribocorrosion of medical implants, and tribocorrosion issues in nuclear power plants, marine environments, automotive cooling circuits and elevated-temperature metal working

This book focuses on the triboemission of low-energy electrons from the freshly generated surface. These electrons play the most crucial role in the chemical reactions at the tribological interface. New models and TIP (thermodymanics of irreversible processes) describe in detail the behavior of emitted electrons which lower the activation energy of the chemical reactions. This book also highlights tribocatalysis phenomena as examples of the lowering of the activation energy. A book titled Tribocatalysis has never been published before this.

In the oral cavity, materials (including our natural teeth) are exposed to a complex environment, which results in simultaneous mechanical, electrochemical, and microbiological solicitations. Therefore, bio-tribocorrosion is an important cause of degradation of dental materials leading to functional and/or biological detrimental effects due to an increased release of metallic ions and wear debris. This chapter describes the main bio-tribocorrosion phenomena that occur in the oral environment, and discuss the main parameters related to both the materials and the environment affecting bio-tribocorrosion in dental applications.

This first edition of Testing Tribocorrosion of Passivating Materials Supporting Research and Industrial Innovation: A Handbook treats in a clear, concise, and practical manner an important material degradation and protection matter. It is designed as a handbook and provides a well structured approach of the basics needed to investigate the tribocorrosion behavior of passivating materials, and to conduct in a correct way a laboratory investigation on it. It provides answers on practical and theoretical approaches of tribocorrosion phenomena to engineers and medical persons involved with material assemblies subjected to aggressive environmental and mechanical conditions. For academic researchers it is a pertinent tool assisting them in how they can perform a tribocorrosion investigation and obtain results that are correctly interpreted and can be exchanged. Different parts of the book are illustrated with practical examples. This handbook is truly an indispensable guide for every professional who comes into contact with the complex material degradation and protection processes that take place under combined corrosion and wear conditions. Fields of interest include: transportation (aeronautics, maritime, rail, automotive), medical implants (orthopaedics, dentistry), biochemistry, food production, energy production, and machining. The coordination of this handbook writing was done by Professor Jean-Pierre Celis (Katholieke Universiteit Leuven, Belgium) and Professor Pierre Ponthiaux (Ecole Centrale Paris, France) assisted by twelve European experts who contributed jointly to the nine chapters of this handbook. Main topics dealt with are tribocorrosion phenomena in medical and industrial sectors, depassivation and repassivation phenomena, impact on synergism in tribocorrosion, specific testing techniques, coupling tribology-to-corrosion, design of a testing protocol, and normalisation.

During their service life, most biomaterials and medical implants are vulnerable to tribological damage. In addition, the environments in which they are placed are often corrosive. The combination of triobology, corrosion and the biological environment has been named ‘bio-tribocorrosion’. Understanding this complex phenomenon is critical to improving the design and service life of medical implants. This important book reviews recent key research in this area. After an introduction to the topography of bio-tribocorrosion, Part one discusses different types of tribocorrosion including fatigue-corrosion, fretting-corrosion, wear-corrosion and abrasion-corrosion. The book also discusses the prediction of wear in medical devices. Part two looks at biological effects on tribocorrosion processes, including how proteins interact with material surfaces and the evolution of surface changes due to bio-tribocorrosion resulting from biofilms and passive films. Part three reviews the issue of bio-tribocorrosion in clinical practice, including dental applications and joint replacement as well the use of coatings and test methods for bio-tribocorrosion. With its international team of contributors, Bio-tribocorrosion in biomaterials and medical implants is a standard reference for those researching and developing medical devices as well as clinicians in such areas as dentistry and orthopaedic surgery. Reviews recent research in bio-tribocorrosion and its role in improving the design and service life of medical implants Discusses types of bio-tribocorrosion including fatigue and wear corrosion Examines biological effects on bio-tribocorrosion processes including interaction of proteins with metal surfaces

It is one oft he major challenges for materials scientists and mechanical engineers to cope with the demands for long lasting and reliable systems in all markets and for all applications. The loss of energy by friction and the limits of endurance by wear can be countered by well selected materials and surfaces. The economical and ecological significance of wear and friction is undisputed and can equate to between 1 and 4% of the gross national products of industrial countries. Although the basic understanding of the mechanisms of friction and wear has drastically increased during the last five decades, many technical solutions are still carried out "following trial and error." Selection of the best material and the optimal topography in combination with the desired physical and chemical properties requires a systematic approach and a deep understanding of the acting mechanisms. Thus friction, wear, and wear protection are interdisciplinary fields which bring together scientists from the engineering, natural, biological and medical sciences. This book is an indispensable source for everybody who needs to solve the problems of friction and wear on materials.

The tribology of miniature systems is quite different from the tribology of large machinery. This is the first publication to cover on an academic level both the basic concepts of the tribology of miniature systems and some areas of its practical application. A comprehensive survey is given on the specific problems encountered in this field, providing a volume that will be useful in solving professional engineering problems in the fast growing field of precision engineering and microtechnology. The suitability of various materials and lubricants for the tribological systems in miniature mechanisms is discussed. The tribological properties and the friction and wear properties which occur in such systems are analysed. Specific lubrication problems are examined in detail; in particular, the use of special tribological coatings to solve many difficult lubrication problems and to obtain high wear resistance of the rubbing elements is considered. The special investigation techniques used to characterize miniature tribological systems and their elements (e.g. lubricants) are reviewed. The tribological aspects of many of the most common assemblies found in miniature mechanism and electromechanism design are analysed and some practical suggestions are put forward for the rational design of such systems. Also special tribological problems such as those met in computer technology, bioengineering, etc. are presented. The book is intended for tribologists (both seasoned researchers and newcomers) studying the problems of this specific branch of tribology and also for practising engineers active in the design, manufacture and exploitation of various miniature systems.
