Available in PDF, EPUB and Kindle. Book excerpt: The nature of interface in contact with skin, clothes or joints is one of the prime interests in the field of metallic biosensors. This interface can be enhanced through PVD processes in terms of chemistry and microstructure. Furthermore, dynamic evaluation of the contact interface at the early stage is essential to better understand the wear mechanism and to anticipate the efficient service life of the corresponding bio-device. Therefore, within this thesis, a laboratory-made micro-tribometer was developed and presented. This particular reciprocating ball-on-disk stage is coupled with an environmental SEM (eSEM) to characterise, at small scale, the tribological behaviour of the system under realistic in situ conditions. To express the proof of concept, a preliminary analysis was performed with a conventional TiN PVD hard coatings, used as a model surface. The testing procedure for the dynamic approach during the run-in period throughout 100 cycles was defined in the controlled atmosphere in eSEM chamber (both in high vacuum and 50% relative humidity (RH)). When the tribological tests were performed, the wear track of the films was examined in situ after every 10 cycles, while the ball track was analysed in post mortem mode. Once validated, the mini-tribometer stage was applied for a more realistic metal used in biosensor systems: titanium. Indeed, this metal presents a high biocompatible character, coupled with interesting mechanical properties. The wear character of pure Ti film is still an issue, due to its columnar microstructure, which can be modified with an addition of proper alloying elements. In this sense, silver is an outstanding material to be alloyed with titanium for bio-sensor applications regarding its anti-bacterial character and ductile nature, as well its remarkable sliding behaviour in nanoparticle form. Within this thesis, Ti-Ag films were deposited with magnetron sputtering PVD process with several Ag contents. Various types of multiscale characterization (microstructural, chemical, electrical, mechanical) were performed to analyse the effect of Ag in the film composition. It was shown that increasing Ag content led to a denser microstructure with Ag-based nano-/micro-meter sized clusters distributed into the film matrix. Moreover, from a functional point of view, it also provided a slight improvement on hardness, Young's modulus and electrical conductivity of the films. During the in situ tribological analysis, the small-scale strategy of characterization that was specifically developed in this PhD, has highlighted a strong influence of the contact environment on its tribological behaviour. In particular, the effect of the humidity rate of the contact region on the tribological behaviour was deeply investigated, and the effect of Ag content on tribological behaviour of Ti-Ag films was studied. It was seen that temperature change to modify the humidity affects the tribological behaviour of polymer counter-face and Ag.

Available in PDF, EPUB and Kindle. Book excerpt: This book broadens the knowledge of tribology. This book is evolved out of current research trends on tribological performance of systems related to nano tribology, rheology, engines, polymer brushes, composite materials, erosive wear and lubrication. The book deals with enhancing the ideas on tribological properties, the different types of wear phenomenon and lubrication enhancement. Further, the tribological performance of systems, whether nano, micro or macro-scale, depends upon a large number of external parameters and important among them are temperature, contact pressure and relative speed. Thus, the book focus on the theoretical aspects to industrial applications of tribology.

Available in PDF, EPUB and Kindle. Book excerpt: TRIBOLOGY AND CHARACTERIZATION OF SURFACE COATINGS The book provides updated information on the friction and wear behavior of coatings used in various industrial applications. Surface modification is a cost-effective process of increasing the life of components so that the whole device need not be changed if the surface is worn out. The tribological behavior of biological implants is currently an active topic and a thorough discussion is one of the book’s features. Tribology and Characterization of Surface Coatings explores key issues which are important in the research and development of surface coatings by providing updated information on friction and wear behavior of coatings used in different industrial applications. It covers the various coating deposition techniques, tribological response of nanocomposite coatings, multilayer hardfacing, and wear testing methods for coatings at nanoscale. The use of nanostructures may alter the tribological, characterization, and mechanical properties of the materials. Thermal spraying is the most widely used technique in industry for the deposition of coatings and their tribological properties need to be determined. This book also includes the recent trends in biotribology and the materials used in implants to counter the abrasive wear. Audience The book will serve as a reference to researchers, scientists, academicians, industrial engineers, and students who work in the fields of materials/polymer science and mechanical engineering. Apart from their applications to aerospace and electronics industries, the coatings are also used in the field of biomedical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Metallurgical Coatings and Thin Films 1990 presents the Proceedings of the 17th International Conference on Metallurgical Coatings and 8th International Conference on Thin Films, held in San Diego, California on April 2-6, 1990. It contains 219 papers covering a wide range of topics related to metallurgical coatings and thin films, including high temperature coatings, hard coatings, diamond films, tribology, and ion beam modification. Organized into 99 chapters, this volume begins with a discussion of a thermochemical model for diamond growth from the vapor phase and an experiment in large area diamond coating using a combustion flame torch in its traversing mode. It then explores the properties of diamond films, preparation of diamond-like carbon films using various ion-beam-assisted techniques, deposition of diamond-like films by laser ablation, and coating of cubic BN films on different substrates. The book examines surface processes and rate-determining steps in plasma-induced chemical vapor deposition, and addition of rare earths to improve scale adherence on heat-resisting alloys and coatings. The reader is introduced to high temperature wear and clearance control coatings, thermal barrier coatings, and corrosion resistant coatings. The book also discusses modification of coatings/surfaces to reduce friction; the mechanics of the tribology of thin films systems; mechanochemical interactions in the tribological behavior of materials; analysis and micromechanical testing of tribological coatings; surface modification using directed ion beams; and industrial equipment and processes. This book is a valuable resource for students and researchers interested in metallurgical coatings and thin films.
