Degradation of Implant Materials

This book surveys the degradation of implant materials, reviewing in detail such failure mechanisms as corrosion, fatigue and wear, along with monitoring techniques. Surveys common implant biomaterials, as well as procedures for implant retrieval and analysis.

This book reviews the current understanding of the mechanical, chemical and biological processes that are responsible for the degradation of a variety of implant materials. All 18 chapters will be written by internationally renowned experts to address both fundamental and practical aspects of research into the field. Different failure mechanisms such as corrosion, fatigue, and wear will be reviewed, together with experimental techniques for monitoring them, either in vitro or in vivo. Procedures for implant retrieval and analysis will be presented. A variety of biomaterials (stainless steels, titanium and its alloys, nitinol, magnesium alloys, polyethylene, biodegradable polymers, silicone gel, hydrogels, calcium phosphates) and medical devices (orthopedic and dental implants, stents, heart valves, breast implants) will be analyzed in detail. The book will serve as a broad reference source for graduate students and researchers studying biomedicine, corrosion, surface science, and electrochemistry.

First book since 1985 to focus on the degradation of impant materials Written by international pioneers in the field hailing from a wide variety of disciplines

Auteur

Noam Eliaz is an Associate Professor at Tel-Aviv University, Israel, where he serves as the Head of The Biomaterials and Corrosion Laboratory. He also serves as a Chief Editor of the journal Corrosion Reviews (jointly with Ron Latanision). He received his B.Sc. and Ph.D. (direct track) in Materials Engineering, both cum laude, from Ben-Gurion University. Next, he became the first ever materials scientist to receive, simultaneously, a Fulbright postdoctoral award and a Rothschild postdoctoral fellowship and worked for two years in the H.H. Uhlig Corrosion Laboratory at M.I.T. To-date, he has contributed more than 230 journal and conference publications, including 31 plenary and invited talks, as well as 5 book chapters. In addition to editing this Degradation of Implant Materials book, he has edited a double volume entitled Applications of Electrochemistry and Nanotechnology in Biology and Medicine for the reputed book series Modern Aspects of Electrochemistry (Springer). He has garnered numerous accolades, including the T.P. Hoar Award for the best paper published in Corrosion Science during 2001 (on corrosion of Ti-Ag-based alloys processed by three-dimensional printing for biomedical applications), and NACE International's Herbert H. Uhlig Award (2010) and Fellow Award (2012). His main research interests include environment-induced degradation of materials, failure analysis, Bio-Ferrography, biomaterials (with focus on electrocrystallization of hydroxyapatite and other calcium phosphates), and electrochemical processing (namely, electrodeposition, electroless deposition and electropolishing) of materials.

Texte du rabat

This book focuses on degradation of biomaterials, which is one of the major considerations in their design, processing and use. It introduces the reader to the body environment and to the mechanical, chemical, electrochemical and biological processes that are responsible to the degradation of biomaterials. The outcomes of degradation are discussed in detail. Different failure mechanisms such as corrosion, fatigue, wear, infection and calcification are reviewed, together with experimental techniques for monitoring them. Procedures for implant retrieval and failure analysis are presented. The degradation of a wide spectrum of materials is reviewed, from several kinds of metals to various polymers and composites. A variety of medical devices is analyzed, including hip and knee prostheses, dental implants, permanent and absorbable stents, heart valves, inferior vena cava filters, breast implants, ophthalmic implants, intrauterine devices, and drug delivery devices.

All chapters are written by world renowned experts. Thus, this book is a must-have for anyone wanting to become familiar with this area, including scientists, engineers, implant manufacturers, and venture capitalists. This book will be valuable for materials, mechanical, biomedical and corrosion engineers; biologists and doctors; chemists and electrochemists; surface scientists, and failure analysts.
