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.

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

Total joint replacements (TJR's) are used to replace deteriorating hip joints, knees, shoulders, wrists and fingers for millions of people in modern-day medicine. They are treatments used for patients with severe cases of arthritis or rheumatism which are mostly common in old-aged people. There was a reported 1.2 million total joint replacement surgeries, primary and revised, across the United States between the years 2012 and 2017. Recent research has pointed out the primary concern with TJR's is the loosening of the prosthetic which further causes destruction of the bone tissue following wear corrosion and failure of the implant. In addition, there were a total of 350 000 total hip replacement surgeries in the U.S between the years 2012 and 2017. The most common type of hip replacements is metal on metal hip replacements. They are preferred because of the less total loss of material being removed from the ball and socket during articulation, low chance of dislocation and reduced chance of fracture. The most common types of metals used in Metal on Metal hip replacements are Cobalt Chromate alloys and Titanium alloys. Cobalt Chromate alloys were studied by Haynes in 1900s who showed that the basic binary Cobalt Chromate alloy exhibited high strength and low chemical reactivity. Generally, these alloys have high-wear resistance, high strength, and modulus of elasticity and high corrosion resistance which makes them useful for orthopedic implants. Titanium on the other hand is useful for orthopedic implants because of its inertness in a biochemical environment with mechanical strengths. In this thesis, modular Cobalt Chromate (Co-Cr-Mo) and Titanium (Ti6Al4V) alloys were subjected to continuous fatigue contact in a corrosive biochemical environment. The change in the passive layers of these alloys were observed by electrochemical characterizations during small displacement mechanical loading in different pH environments. Namely, Phosphate Buffer Solution (PBS) with a pH of 7.4, Sodium lactate solution which pH of 4 and 2. To further understand chemo-mechanical synergism, and damage recovery behaviors of two different oxides, a Nano-scratch based experiment was carried out in a tribochemical cell. Cyclic reciprocating motions with an alumina sphere was applied with controlled normal load in the solutions. The open circuit potential and potentiostatic polarization were used to measure the 2 polarization resistance and potential. Changes of electrochemical responses were monitored using the Gamry Potentiometer to quantitatively compare alterations of wear track area, roughness, and oxide thickness on both implant materials during mechanical wear. After thorough investigation, it can be deduced that the formation of oxide layer in the Titanium alloys occurs during fretting, after fretting and in some instances before fretting. CoCrMo however does not re-passivate during fretting but does recover its oxide layer after.

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.

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.

The 27th Leeds-Lyon Symposium on Tribology was held at the Institut National des Sciences Appliquées de Lyon, 5-8 September 2000. The central theme was: 'Tribology Research: From Model Experiment to Industrial Problem: A century of efforts in mechanics, materials science and physico-chemistry'. To celebrate the Year 2000, the organisers tried to achieve two different goals. First, to bring together contributions from the three major scientific fields that make up the Tribological community: mechanics, physico-chemistry and materials science. The second goal was to attract contributions ranging from complex industrial problems to model experiments. The conference began with two keynote lectures, the first being a detailed technical lecture on the dynamic behaviour of an elastic shaft supported by hydrodynamic bearings. The second was an overview of first principles multi-scale modelling of physicochemical aspects of tribology. Both of these interesting lectures are included in the proceedings volume.

Abstract: Biomedical alloys are prone to suffer corrosion and wear phenomena coming from the hostile environment of the body and friction processes, respectively. Diamond-like carbon (DLC) coatings are known to be excellent candidates for using as protective coatings on biomedical alloys, not only due to their excellent tribological properties but also due to their chemical composition and stability. In this work, three Ti-DLC PVD coatings with different compositions were deposited on Ti6Al4V alloy and their corrosion and tribocorrosion responses were evaluated in simulated body fluid. Excellent tribocorrosion response has been found especially in case of coatings with high carbon content. Additionally significative reduction of friction and wear has been obtained in comparison to the substrate response. Highlights: Three DLC coatings were deposited on Ti grade 5 by changing PVD process parameters. Different process parameters provide different tribo-chemical response. Three DLC coatings have excellent corrosion response and electrochemical stability. DLC coatings reduced friction by 64%. Coatings strongly decrease the wear rates due to tribocorrosion by 98–100%.
