Available in PDF, EPUB and Kindle. Book excerpt: The need for toxic chromate replacements in metal-finishing industries has prompted an intensive search for replacement technologies in recent years. Organofunctional silanes have emerged as an outstanding, environment friendly corrosion protectors of metal substrates for replacing the conventional chromate treatments. It has been recently demonstrated that electrodeposition of silane films on metal surfaces results in improvement of corrosion protection compared to the conventional coating methods like dip coating and spray coating. It has also been proved that uniformity and better control over the thickness of the coating can be achieved by electrodeposition. This thesis dissertation consists of two parts: (1) Identification of a novel silane, which produces comparatively hydrophobic, corrosion resistant film. (2) Development of a new volatile organic content (VOC)-free, water-based silane system. Various combinations of silane mixtures were tested at different voltages, pH's, bath concentrations and exposure times on panels of aluminum alloys. The film formed was characterized mainly using electrochemical, surface and interfacial characterization techniques. Application of time of flight secondary ion mass spectroscopy (TOF-SIMS) to electrodeposited films has provided direct evidence for the presence of O2 Al(O-Si-O)and OAl(O-Si-O)2 groups at the silane-aluminum oxide interface. Also pulsed electrodeposition (alternating positive and negative voltage) of silanes were studied which show better performance, as anodization of the aluminum oxide layer is achieved and the silane film reacts with the metal oxide in a different way.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers a broad range of materials science that has been brought to bear on providing solutions to the challenges of developing self-healing and protective coatings for a range of metals. The book has a strong emphasis on characterisation techniques, particularly new techniques that are beginning to be used in the coatings area. It features many contributions written by experts from various industrial sectors which examine the needs of the sectors and the state of the art. The development of self-healing and protective coatings has been an expanding field in recent years and applies a lot of new knowledge gained from other fields as well as other areas of materials science to the development of coatings. It has borrowed from fields such as the food and pharmaceutical industries who have used, polymer techniques, sol-gel science and colloidosome technology for a range encapsulation techniques. It has also borrowed from fields like hydrogen storage such as from the development of hierarchical and other materials based on organic templating as “nanocontainers” for the delivery of inhibitors. In materials science, recent developments in high throughput and other characterisation techniques, such as those available from synchrotrons, are being increasing used for novel characterisation – one only needs to look at the application of these techniques in self healing polymers to gauge wealth of new information that has been gained from these techniques. This work is largely driven by the need to replace environmental pollutants and hazardous chemicals that represent risk to humans such as chromate inhibitors which are still used in some applications.

Part two then considers the metallurgical effect in relation to the corrosion of magnesium alloys, including the role of micro-structure and earth-rare elements, the corrosion behaviour of magnesium-based bulk metallic glasses, and the corrosion of innovative magnesium alloys. Part three goes on to describe environmental influences on the corrosion of magnesium alloys, such as atmospheric corrosion, stress corrosion cracking, creep and fatigue behaviour, and galvanic corrosion. Finally, part four is concerned with various means of protecting magnesium alloys against corrosion through the use of aluminium electrodeposition, conversion and electrophoretic coatings, and anodisation. With its distinguished editor and team of contributors, this book is an invaluable resource for metallurgists, engineers and designers working with magnesium and its alloys, as well as professionals in the aerospace and automotive industries.

Download or read book Silane Coupling Agents written by Edwin P. Plueddemann and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: * It has been rumored that a bumble bee has such aerodynamic deficiencies that it should be incapable of flight. Fiberglass-reinforced polymer com posites, similarly, have two (apparently) insurmountable obstacles to per formance: 1) Water can hydrolyze any conceivable bond between organic and inorganic phase, and 2) Stresses across the interface during temperature cycling (resulting from a mismatch in thermal expansion coefficients) may exceed the strength of one of the phases. Organofunctional silanes are hybrid organic-inorganic compounds that are used as coupling agents across the organic-inorganic interface to help overcome these two obstacles to composite performance. One of their functions is to use the hydrolytic action of water under equilibrium condi tions to relieve thermally induced stresses across the interface. If equilib rium conditions can be maintained, the two problems act to cancel each other out. Coupling agents are defined primarily as materials that improve the practical adhesive bond of polymer to mineral. This may involve an increase in true adhesion, but it may also involve improved wetting, rheology, and other handling properties. The coupling agent may also modify the inter phase region to strengthen the organic and inorganic boundary layers.
