This book was released on 1994 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The in-vitro behavior of hydroxyapatite (HAp) coatings depends on the thermal history of the coating after thermal spraying. As-sprayed amorphous coatings degrade in Ringer's solution. Heat treatment at 800 °C for 2 hours produces a crystalline coating which upon immersion in physiological solution displays a greater stability. Coatings are characterized for surface morphology, composition, crystallinity, roughness, and weight loss. The as-sprayed coating shows changes in the coating morphology with immersion time. Individual lamellae crack and separate from the coating. Those lamellae still intact show evidence of dissolution. After a period of 8 weeks small HAp spheres cover the surface of the as-sprayed and heat treated coatings. These morphological changes are expected to influence the rate of bone bonding. Therefore post-treatment of HAp coatings is seen as a technique to alter or control implant-tissue interactions.

Download or read book Advanced Plasma Spray Applications written by Hamidreza Salimi Jazi and published by BoD – Books on Demand. This book was released on 2012-03-21 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, plasma spray has been received a large number of attentions for various type of applications due to the nature of the plasma plume and deposition structure. The plasma gas generated by the arc, consists of free electrons, ionized atoms, some neutral atoms, and undissociated diatomic molecules. The temperature of the core of the plasma jet may exceed up to 30,000 K. Gas velocity in the plasma spray torch can be varied from subsonic to supersonic using converging-diverging nozzles. Heat transfer in the plasma jet is primarily the result of the recombination of the ions and re-association of atoms in diatomic gases on the powder surfaces and absorption of radiation. Taking advantages of the plasma plume atmosphere, plasma spray can be used for surface modification and treatment, especially for activation of polymer surfaces. I addition, plasma spray can be used to deposit nanostructures as well as advanced coating structures for new applications in wear and corrosion resistance. Some state-of-the-art studies of advanced applications of plasma spraying such as nanostructure coatings, surface modifications, biomaterial deposition, and anti wear and corrosion coatings are presented in this book.

Available in PDF, EPUB and Kindle. Book excerpt: Reflecting the progress in recent years, this book provides in-depth information on the preparation, chemistry, and engineering of bioceramic coatings for medical implants. It is authored by two renowned experts with over 30 years of experience in industry and academia, who know the potentials and pitfalls of the techniques concerned. Following an introduction to the principles of biocompatibility, they present the structures and properties of various bioceramics from alumina to zirconia. The main part of the work focuses on coating technologies, such as chemical vapor deposition, sol-gel deposition and thermal spraying. There then follows a discussion of the major interactions of bioceramics with bone or tissue cells, complemented by an overview of the in-vitro testing methods of the biomineralization properties of bioceramics. The text is rounded off by chapters on the functionalization of bioceramic coatings and a look at future trends. As a result, the authors bring together all aspects of the latest techniques for designing, depositing, testing, and implementing improved and novel bioceramic coating compositions, providing a full yet concise overview for beginners and professionals.
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.

Download or read book The Testing of Plasma Spray Coatings written by T. J. Roseberry and published by . This book was released on 1976 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This program was conducted for the purpose of providing reference data on plasma-sprayed coatings for use in the design and repair/salvage of naval ordnance hardware. Plasma-spray deposition parameters and surface finishing techniques were developed for metal and ceramic plasma-sprayed coatings applied to mild steel, stainless steel, aluminum, brass, and K-monel. The wear characteristics of the coated shafts versus a variety of bushing materials were studied in hydraulic piston wear tests during which oil leakage rates as a function of surface finish were determined using Teflon and urethane seal materials. As a result of the program, plasma-sprayed coatings and bushing material were identified that provided friction and wear performance at least comparable to that provided by baseline conventional cylinder materials. Teflon seals were found to provide the most reliable dynamic seal performance, and a low viscosity, polyester type resin sealer (Loctite 290) was found to be an effective sealant for both hydraulic and pneumatic applications. The plasma-spray parameters and processing parameters and techniques developed in this program and information on the coating properties and process limitations derived from this work will be incorporated in the plasma-spray handbook being prepared for NOSL under Contract No. N-00197-73-C-0430.
