Summary : 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

Summary : Total joint replacement (TJR), or joint arthroplasty, is a widely used surgical procedure in which the entire joint is removed and replaced with a prosthetic joint. The most common types of TJR are total hip replacement (THR) and total knee replacement (TKR). The improvement and development of safer, longer lasting and better functioning implants are essential. Recent reports of potential problems caused by ion release in metal-on-metal (MoM) TJRs resulting in the formation of pseudo-tumours therefore need to be properly investigated. This chapter provides an overview of the evolution of TJR, followed by a review of the issues and the science around ion release. The potential corrosion issues and bio-tribocorrosion processes which prevail in TJRs, including orthopaedic implant materials, load-bearing joint replacement materials tribocorrosion, and protein adsorption, are also discussed.

Summary : 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

Summary : Articulating systems are complex mechanical systems operating under sliding, rotation, slip, vibrations, weight bearing, and loading conditions. A problem in mechanical systems is the occurrence of tribocorrosion, involving a synergism between corrosion and mechanical wear, and causing increased material degradation. A tribocorrosion protocol allowing separation of the mechanical, corrosive and synergetic contributions to the total loss of material is described, based on electrochemical measurements performed before and during unidirectional sliding. As a case study, the protocol is implemented to test the tribocorrosion resistance of CoCrMo alloys under sliding. The different components of the total wear related to corrosive and mechanical contributions are calculated.

Summary : Tribocorrosion occurs in all walks of life from energy conversion to hip joints and dental implants. However, the materials required, and control of processes to limit the tribo-corrosion degradation are often not well understood. Tribocorrosion for Materials Engineers describes the various tribocorrosion processes, including wear phenomena, the Pourbaix diagram for aqueous corrosion, and the thermodynamic stability diagram for high temperature oxidation. It highlights the work done during in the past 20 years on tribocorrosion maps where both tribology and corrosion mapping approaches are combined. The author addresses erosion, abrasion (and microscale-abrasion), fretting and sliding wear interactions with corrosion. He also traces theoretical development and validation from practical experimental data with respect to the literature. The then discusses recent mapping approaches using CFD techniques. An examination of the latest thinking on the subject, the book details tribocorrosion issues in dentistry, bio-implants such as hip joint replacements and renewable energies such as tidal and offshore wind as well as space will be addressed in addition to more conventional oil/gas environments. It also discusses best practice in testing tribocorrosion over a multi-parameter space, enabling the production of such maps, with respect to current international standards in the subject.

Summary : Wear can be defined as a process where interaction between two surfaces or bounding faces of solids within the working environment results in dimensional loss of one solid, with or without any actual decoupling and loss of material. Wear may accelerate corrosion that involves chemical or electrochemical reactions between materials. Both these phenomena fall under the broader category of tribocorrosion. The interactions of mechanical loading and chemical/electrochemical reactions that occur between the elements of a tribological system exposed to biological environments constitute bio-tribocorrosion science.

Summary : 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.

Summary : The tribological performance of implant materials within the body where the pH can vary between 7.4 and 4.0, depending on whether the joint is infected or not, is extremely harsh and varies significantly from that experienced in other engineering environments. Three wear mechanisms that affect biomedical and, in particular, orthopaedic implants are regularly reported. These are adhesion, abrasion and fatigue. The wear mechanisms in biomedical implants, particularly hip joints, are reported to be a function of the following variables: type of materials used, contact stresses, lubricants and clearance, surface hardness and roughness, type of articulation due to motion, number of cycles, solution particle count and distribution, and tribocorrosion.

Summary : During the last few years, tribocorrosion evaluation of artificial joints has become an attractive research area for biomedical scientists and medical professionals. This particular field of study deals with a complex artificial human joint system and many unknown parameters. In this chapter an attempt is made through the perspective of a clinician to bring some insights into this area of research. This chapter addresses the basic tribocorrosion aspects of artificial joints and their clinical implications, beginning with clinical problems, cell responses to the presence of metal particles and ions, and evidence of tribocorrosion from retrieved implants. Then comparisons are made between in vivo and in vitro test conditions, and the complex nature of in vivo joint conditions is discussed. Finally, novel case studies (influence of protein and environment, evidence of synergistic interactions between corrosion and wear) on the research of tribocorrosion of metal-on-metal (MoM) hip joints are also included.

Summary : 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.

Summary : Two materials (one being metal) under slight relative motion in a liquid medium are subjected to fretting corrosion. This chapter is dedicated to studying fretting corrosion of implants. After describing the most significant implants subjected to fretting, fretting corrosion is defined. Fretting corrosion is a particular degradation mechanism; it highlights the key role of passive film, crevice corrosion, etc. For demonstrating the electrochemical effect of the fretting corrosion of metal, some investigations are presented at free corrosion potential and at applied potential to measure the specific current density. Moreover, the role of proteins is investigated because they constitute the biological environment and thus play a significant role in fretting corrosion processes. Finally, results from atomic force microscopy (AFM) show the particular debris, size about 100nm. The problem of debris influence is discussed.

Summary : This chapter discusses synergistic damage mechanisms of modular implants due to mechanical stimulus and electrochemical dissolution. The influences of contact loads, plastic deformation, residual stresses, and environmental conditions are focused to illustrate mechanisms of damage and dissolution. Fretting corrosion is the most prevalent phenomenon that degrades the mechanical and chemical properties of implant materials. It has been explained as an alternating process of fracture and unstable growth of metal oxide film during fatigue contact motion in the corrosive environment. Stress-dependent electrochemical dissolution has also been identified as one of the key mechanisms governing surface degradation in fatigue contact and crevice corrosion of biomedical implants. This damage mechanism incorporates contact-induced residual stress development and stress-assisted dissolution. Understanding of the corrosion damage mechanism of metallic implants is very important in predicting the useful life of implants and optimizing the design of orthopedic implants.
