Synopses & Reviews
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 key recent 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. Chapters also explain 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. The concluding section reviews the issue of bio-tribocrrosion in clinical practice, including dental applications and joint replacement as well the use of coatings and test methods for bio-tribocorrosion.
As the use of implanted biomaterials increases, issues relating to their long-term durability need to be addressed. The science of bio-tribocorrosion is concerned with implant surface changes resulting from interactions (such as loading and chemical reactions) that occur within the bodily environment. Expert contributors discuss the processes of bio-tribocorrosion that will help achieve safer and more durable implants. Chapters discuss the fundamentals of bio-tribocorrosion, wear-corrosion mechanisms, the biological environment and bio-tribocorrosion in the clinical environment.
