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

Sliding Tribo-Corrosion of Passive Metals

Sliding Tribo-Corrosion of Passive Metals PDF Author: S. Mischler
Publisher:
ISBN:
Category : Corrosion and anti-corrosives
Languages : en
Pages : 18

Book Description
Recently developed concepts in the mechanistic modeling of tribo-corrosion are evaluated. In particular, the paper analyzes the applicability of recently developed galvanic coupling models, the combination of Archard's type models and Hertzian contact formalisms for predicting corrosion rates under sliding conditions, and the implications of tribologically induced microstructural transformations for the mechanical response of metals during tribo-corrosion. Galvanic coupling models were found to be very promising tools, but they do need to be refined. The relevance of mechanical damage in the nano-crystalline layers during tribo-corrosion is shown.

Publisher: Elsevier
ISBN: 0857098608
Category : Technology & Engineering
Languages : en
Pages : 434

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
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.

Book Description
This is the first text that deals specifically with TMJ TJR. Each chapter is authored by either a basic science researcher or clinician known for their interest and expertise in this field. The text provides the reader with state-of-the-art analysis of all aspects of total temporomandibular joint replacement (TMJ TJR), starting with cutting-edge evidence on the biomechanics of the TMJ. The intriguing history of TMJ TJR is presented to provide an understanding of why some prior TMJ TJR devices failed and how what was learned from those failures has led to the improvements exhibited in present TMJ TJR devices. Expert chapters discuss both stock and custom designs, their indications and contraindications, primary operative techniques, combined TMJ TJR and orthognathic surgical techniques, and the devices' adaption for use as segmental or total mandibular replacement devices after ablative surgery. Clinical outcomes and avoidance as well as management of complications are detailed. Numerous helpful illustrations and radiographs are presented to assist readers in understanding and carrying out the described procedures. Important evidence from both the orthopedic and TMJ TJR literature relating to material sensitivity and mechanical wear will be reported. Finally, the role bioengineered tissue may hold for the future of TMJ TJR will be discussed.
