Tribocorrosion of Passive Metals and Coatings


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




Bio-Tribocorrosion in Biomaterials and Medical Implants


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




Bio-tribocorrosion in biomaterials and medical implants


Book Description

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.

Tribocatalysis, Tribochemistry, and Tribocorrosion


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.




Bio-tribocorrosion in biomaterials and medical implants


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.
