Download or read book Hydroxyapatite Coatings for Biomedical Applications written by Sam Zhang and published by CRC Press. This book was released on 2013-05-14 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydroxyapatite coatings are of great importance in the biological and biomedical coatings fields, especially in the current era of nanotechnology and bioapplications. With a bonelike structure that promotes osseointegration, hydroxyapatite coating can be applied to otherwise bioinactive implants to make their surface bioactive, thus achieving faster healing and recovery. In addition to applications in orthopedic and dental implants, this coating can also be used in drug delivery. Hydroxyapatite Coatings for Biomedical Applications explores developments in the processing and property characterization and applications of hydroxyapatite to provide timely information for active researchers and newcomers alike. In eight carefully reviewed chapters, hydroxyapatite experts from the United States, Japan, Singapore, and China present the latest on topics ranging from deposition processes to biomedical applications in implants and drug delivery. This book discusses: Magnetron sputtering and electrochemical deposition The modification of hydroxyapatite properties by sol–gel deposition to incorporate other elements found in natural bones, such as zinc, magnesium, and fluorine The use of pure hydroxyapatite in drug delivery applications The growth or self-assembly of hydroxyapatite on shape memory alloy Hydroxyapatite composite coatings—with carbon nanotubes, titanium dioxide (TiO2), and others—on the titanium alloy Offering valuable insights and a wealth of data, including numerous tables and figures, this is a rich source of information for research on hydroxyapatite coatings. Each chapter also covers material that provides an accessible stepping stone for those who are new to the field.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the properties of biomaterials that have found wide clinical applications, while also reviewing the state-of-the-art in the development towards future medical applications, starting with a brief introduction to the history of biomaterials used in hip arthroplasty. The book then reviews general types of biomaterials – polymers, ceramics, and metals, as well as different material structures such as porous materials and coatings and their applications – before exploring various current research trends, such as biodegradable and porous metals, shape memory alloys, bioactive biomaterials and coatings, and nanometals used in the diagnosis and therapy of cancer. In turn, the book discusses a range of methods and approaches used in connection with biomaterial properties and characterization – chemical properties, biocompatibility, in vivo behaviour characterisation, as well as genotoxicity and mutagenicity – and reviews various diagnostic techniques: histopathological analysis, imagining techniques, and methods for physicochemical and spectroscopic characterization. Properties of stent deployment procedures in cardiovascular surgeries, from aspects of prediction, development and deployment of stent geometries are presented on the basis of novel modelling approaches. The last part of the book presents the clinical applications of biomaterials, together with case studies in dentistry, knee and hip prosthesis. Reflecting the efforts of a multidisciplinary team of authors, gathering chemical engineers, medical doctors, physicists and engineers, it presents a rich blend of perspectives on the application of biomaterials in clinical practice. The book will provide clinicians with an essential review of currently available solutions in specific medical areas, also incorporating non-medical solutions and standpoints, thus offering them a broader selection of materials and implantable solutions. This work is the result of joint efforts of various academic and research institutions participating in WIMB Tempus project, 543898-TEMPUS-1-2013-1-ES-TEMPUS-JPHES, "Development of Sustainable Interrelations between Education, Research and Innovation at WBC Universities in Nanotechnologies and Advanced Materials where Innovation Means Business", co-funded by the Tempus Programme of the European Union.

This book was released on 1985 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of this work was to determine mechanical properties of implants with graded porous coatings without reference to the properties of the ingrown bone. Optimum strength of a bone/implant interface consisting of porous metal and ingrown bone requires a gradation from base metal to the original bone. The composite metal-bone interface can be obtained by applying a metal coating of graded porosity, varying from near zero at the substrate surface to more than 50% at the outermost layer, on the original implant. Graded porous coatings of titanium or Ti-6Al-4V were obtained by plasma spraying of selected particle size fractions in three layers of successively decreasing density, the top coat being made with 300 to 850 ?m powder. Tensile and shear strengths of the coatings were determined by cementing coated samples face to face with an adhesive resin to simulate ingrown bone. Data from these tests are given. Shear strength values ranged from 5.6 to 9.9 MPa (815 to 1430 psi) and tensile strength values were 5.1 to 25.5 MPa (745 to 3700 psi). Failure occurred within the porous coating and not at the interface between the substrate and the coating. Corrosion fatigue tests in Hanks' solution at 37°C (98.6°F) and a pH of 7.4, with a cyclic, fully reversed, peak torsional shear strain of ±0.01, gave lifetimes comparable to or better than those reported for mill-annealed Ti-6Al-4V, except for the samples that had been sintered.

Download or read book Development of a Hydroxyapatite Coating on AZ31 Magnesium Alloy for Use in Biodegradable Implants written by Madila Awalini and published by . This book was released on 2015 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Known to have poor corrosion resistance for general engineering applications, magnesium alloys have recently attracted great interest among researchers for use as biodegradable osteo-implants. The extremely low corrosion resistance of these alloys, which has been a major drawback for its use as light-weight surgical implants, is an advantage point for the application of biodegradable implants. Ideally, biodegradable implants should have a controllable dissolution rate, or in other words, a delayed corrosion reaction on its surface to maintain mechanical integrity until the bone restores itself. Thereafter, the implant should be degraded over time in a controlled manner and reabsorbed safely into the body as the healing process is completed – so that no secondary surgery is needed to remove the implants. The main challenge in this research work is to investigate an approach of improving corrosion resistance of AZ31 Magnesium alloy, by introducing a corrosion-rate controlling layer between the implant material and the body fluid. This research work explores the use of plasma spray as the deposition method for applying the hydroxyapatite (HAp) coatings on AZ31 substrates. The spray parameters used in all trials have successfully led to production of a porous coating structure specifically designed for corrosion-rate controlling layer for biodegradable implants. Corrosion-tested samples were characterised to evaluate their degradation behaviour to establish an understanding of the corrosion mechanism of the designed coating system in this work. An improved corrosion resistance has been achieved by applying a plasma-sprayed HAp coating on bare AZ31 material, in which the corrosion rate is slower than that of uncoated material. Additionally, the carbonate treatment of the HAp-coated AZ31 has successfully enhanced the corrosion characteristic of the designed coating system. Despite the fact that AZ31 is corroding due to the presence of corrosive medium at the substrate-coating interface area, the coating is still adherent to allow a controlled degradation mechanism - thus preventing a catastrophic failure of the designed coating system.
