Book Description
The use of polymer matrix composites (PMCs) in the gas flow path of advanced turbine engines offers significant benefits for aircraft engine performance but their useful lifetime is limited by their poor erosion resistance. High velocity oxy-fuel (HVOF) sprayed polymer/cermet functionally graded (FGM) coatings are being investigated as a method to address this technology gap by providing erosion and oxidation protection to polymer matrix composites. The FGM coating structures are based on a polyimide matrix filled with varying volume fractions of WC-Co. The graded coating architecture was produced using a combination of internal and external feedstock injection, via two computer-controlled powder feeders and controlled substrate preheating. Porosity, coating thickness and volume fraction of the WC-Co filler retained in the coatings were determined using standard metallographic techniques and computer image analysis. The pull-off strength (often referred to as the adhesive strength) of the coatings was evaluated according to the ASTM D 4541 standard test method, which measured the greatest normal tensile force that the coating could withstand. Adhesive/cohesive strengths were determined for three different types of coating structures and compared based on the maximum indicated load and the surface area loaded. The nature and locus of the fractures were characterized according to the percent of adhesive and/or cohesive failure, and the tested interfaces and layers involved were analyzed by Scanning Electron Microscopy.

Book Description
This fully revised, industry-standard resource offers practical details on every aspect of the fundamentals necessary for understanding thermal spray technology, from powder all the way to the final part. The second edition is presented in a reader-friendly format that is split into four parts. Part I presents a review of thermal spray coating and its position in the broad field of surface modification technologies. Highlights of combustion and thermal plasmas are given with an expanded treatment of in-flight plasma-particle interactions. The second and third parts deal respectively with an updated presentation of thermal spray technologies and coating formation, including solution and suspension plasma spraying. The last part of the book includes a comparative analysis of different thermal spray processes, which is essential for the optimal selection of the appropriate thermal spray process in a given application. Coverage of system integration has been expanded with the addition of a detailed discussion of online instrumentation and process diagnostics and numerous examples of industrial scale spray booth designs. Attention is also given to coating finishing and health and safety issues. An extensive review is presented of thermal spray applications grouped in terms of process objectives and present use in different industrial sectors. This book will serve as an invaluable resource as a textbook for graduate courses in the field and as an exhaustive reference for professionals involved in the thermal spray field.

Book Description
Despite advances in alternative materials, metals are still the biomaterial of choice for a number of clinical applications such as dental, orthopedic and cardiac implants. However, there are a number of intrinsic problems associated with implanting metal in the biological environment, such as wear, corrosion, biocompatibility and toxicity, which must be addressed. Modern technology has enabled scientists to modify metal surfaces or apply special coatings to metals to improve their performance safety. Surface Coating and Modification of Metallic Biomaterials will discuss the most important modification techniques and coatings for metals, first covering the fundamentals of metals as a biomaterial and then exploring surface modification techniques and coatings. - An expansive overview of surface modification techniques for biomedical use - In-depth exploration of issues arising from metal biomaterial use - Includes examples of applications in a clinical setting
