Book Description :

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

Book Description :

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.

Book Description :

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

Book Description :

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.

Book Description :

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%.

Book Description :

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.

Book Description :

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.

Book Description :

Prosthetic implants have helped to restore mobility and increase the function of diseased joints. The modular design of joint replacement is most widely used due to the ease of anatomic customization. Modular interface such as the stem-head interface of total hip replacements is continuously subjected to wear and corrosion. CoCrMo and Ti6Al4V ELI are the most widely used metals in Total Hip Joint Replacement implant devices because of their long life, high mechanical strength, and electrochemical stability. Tribocorrosion behavior study of both metals is essential to predict the actual performance of these metals in implant and to judge which metal is better over others. The scratch test and electrochemistry of corrosion is performed on both metals to see wear behavior at varying Normal load. Three different loads were used on both metals to get a broader view. Open Circuit Potential (OCP) and Potentiostatic Polarization Resistance were measured to analyze corrosion behavior of metal along with mechanical wear by scratching the flat surface with the micromotion of the spherical ball. Potentiodynamic Polarization Resistance (PPR) were measured for corrosion behavior during an ideal condition when there is no mechanical wear. OCP measurement revealed that Ti6Al4V ELI exhibits depassivation for first few cycles of scratch but started repassivation soon with periodic depassivation. While on CoCrMo depassivation was more than repassivation resulting in continuous small drops during fretting. Ti6Al4V ELI showed better corrosion resistance at all loads during fretting. After fretting was ceased, repassivation was faster in CoCrMo than Ti6Al4V ELI. The coefficient of friction (COF) measurement during scratching is beneficial for predicting the material removal and wear debris arrest between contacting surface. PPR measurement yielded a wider range of passive zone for Ti6Al4V ELI when swept through negative to positive voltage. Potentiostatic Polarization at three different voltage resulted in an increase in current density from baseline only in CoCrMo along with scratch at three loads. Ti6Al4V ELI was passive at all three voltage and all three loads. CoCrMo showed a higher change in current density at a higher voltage and load.

Book Description :

Abstract: Tribocorrosion is an important failure cause of High-Strength Low-Alloy steel (HSLA) components in offshore applications due to the synergistic effect of wear and the corrosiveness of seawater. In this work, the effect of temperature on the tribocorrosion behaviour of two steel grades has been investigated by performing tribocorrosion tests under reciprocating sliding at two electrolyte temperatures. The total material loss due to corrosion in the unworn surface and due to tribocorrosion in the wear track was quantified. Sliding was found to accelerate the corrosion in the unworn area. Furthermore, temperature was confirmed to have an important effect on the tribocorrosion behaviour of the steels, in terms of higher material losses due to corrosion at higher test temperature. Highlights: The influence of temperature on the tribocorrosion behaviour of two mooring steel grades was studied. Bidirectional sliding wear tests were performed at two electrolyte temperatures (2 °C and 23 °C). The corrosion resistance decreased considerably during sliding, specially at 23 °C. The principal cause of material loss was tribocorrosion in the wear track. The material loss due to pure corrosion was more than two times higher at 23 °C.
