Spray


Book Description

Five teenagers enrol in a play assassination game in a fictional city: Shell, a student, with a perky exterior hiding a vulnerable need to prove herself, falls for Mac when required to assassinate him; Mac a student drop out, resentful of his parents' divorce a year before the story starts, what he doesn't know is that his sister Han has joined the game to find him; Green, a computer geek, is overweight and has issues with self-esteem, like Shell he sees the game as a chance to prove himself as well as interact with people his own age; Zed is feisty and attractive and a metal head goth by night, by day a student nurse - Zed is a chameleon and pretty ruthless, the most competitive of all perhaps, but does she know who she really is? The buzz in this 'street war' is that you feel like a player in a real action movie with all of the adrenalin and the strategy and the pace, without the danger The game is organised online by the elusive 'gamekeeper' and all players meet him once, to collect the details of their first target on a laminated card ... Meanwhile their name is also down as a target, for whom, they don't know...all they know is that they have to be on their guard, always looking over their shoulder, ready to dodge their 'assailant'. These five teens have their own stories to tell, their own relationships unresolved, for some the game and the end result is more important than others. But what becomes clear, as the plot and the game unravels, is that the danger is more real than they thought, and that the Gamekeeper has a shady agenda of his own.




Cold Spray Technology


Book Description

The topic of this book is Cold Spray technology. Cold Spray is a process of applying coatings by exposing a metallic or dielectric substrate to a high velocity (300 to 1200 m/s) jet of small (1 to 50 μm) particles accelerated by a supersonic jet of compressed gas. This process is based on the selection of the combination of particle temperature, velocity, and size that allows spraying at the lowest temperature possible. In the Cold Spray process, powder particles are accelerated by the supersonic gas jet at a temperature that is always lower than the melting point of the material, resulting in coating formation from particles in the solid state. As a consequence, the deleterious effects of high-temperature oxidation, evaporation, melting, crystallization, residual stresses, gas release, and other common problems for traditional thermal spray methods are minimized or eliminated. This book is the first of its kind on the Cold Spray process. Cold Spray Technology covers a wide spectrum of various aspects of the Cold Spray technology, including gas-dynamics, physics of interaction of high-speed solid particles with a substrate as well as equipment, technologies, and applications. Cold Spray Technology includes the results of more than 20 years of original studies (1984-2005) conducted at the Institute of Theoretical and Applied Mechanics of the Siberian Division of the Russian Academy of Science, as well as the results of studies conducted at most of the research centres around the world. The authors' goal is threefold. The first goal is to explain basic principles and advantages of the Cold Spray process. The second goal is, to give practical information on technologies and equipment. The third goal is to present the current state of research and development in this field over the world. The book provides coverage and data that will be of interest for users of Cold Spray technology as well as for other coating experts. At the present time the Cold Spray method is recognized by world leading scientists and specialists. A wide spectrum of research is being conducted at many research centres and companies in many countries. New approach to spray coatings Results are exceptionally pure coatings Low spray temperature without degradation of powder and substrate materials High productivity, high deposition efficiency High operational safety because of absence of high temperature gas jets, radiation and explosive gases Excellent thermal and electrical conductivity Wide spectrum of applications because of important advantages of the process




Modern Cold Spray


Book Description

This book focuses on the current state of the art of the novel cold spray process. Cold spray is a solid state metal consolidation process, which allows engineers to tailor surface and shape properties by optimizing process parameters, powder characteristics and substrate conditions for a wide variety of applications that are difficult or impossible by other techniques. Readers will benefit from this book's coverage of the commercial evolution of cold spray since the 1980's and will gain a practical understanding of what the technology has to offer.

The Cold Spray Materials Deposition Process


Book Description

The cold spray process produces dense, low oxide coatings which can be used in such diverse applications as corrosion control and metals repair. It has emerged as an important alternative to thermal spray coating techniques in certain areas. This pioneering book reviews both the fundamentals of the process and how it can best be applied in practice. The first part of the book discusses the development of the process together with its advantages and disadvantages in comparison with thermal spray coating techniques. Part two reviews key process parameters such as powders, nozzle design, particle temperature and velocity, and particle/substrate interaction. It also describes portable and stationary cold spray systems. The final part of the book discusses how the cold spray process can be applied in such areas as improved wear, corrosion protection, electromagnetic interference shielding and repair of damaged components. The cold spray materials deposition process is a standard reference on this important process and its industrial applications. Examines the fundamentals of the cold spraying process Assesses how the technique can best be applied in practice Describes portable and stationary cold spray systems




Thermal Spray Fundamentals


Book Description

This book provides readers with the fundamentals necessary for understanding thermal spray technology. Coverage includes in-depth discussions of various thermal spray processes, feedstock materials, particle-jet interactions, and associated yet very critical topics: diagnostics, current and emerging applications, surface science, and pre and post-treatment. 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 thermal spray technology.




Spray Nation


Book Description

Culled from the extensive archives of one of the most renowned graffiti photographers of all time comes this remarkable collection of previously unpublished images of New York’s graffiti scene in the 1980s. If you were a graffiti writer in 1980s New York City, you wanted Martha Cooper to document your work—and she probably did. Cooper has spent decades immortalizing art that is often overlooked, and usually illegal. Her first book, 1984’s Subway Art (a collaboration with Henry Chalfant), is affectionately referred to by graffiti artists as the “bible”. To create Spray Nation, Cooper and editor Roger Gastman pored through hundreds of thousands of 35mm Kodachrome slides, painstakingly selecting and digitizing them. The photos range from obscure tags to portraits, action shots, walls, and painted subway cars. They are accompanied by heartfelt essays celebrating Cooper’s drive, spirit, and singular vision. The images capture a gritty New York era that is gone forever. And although the original pieces (as well as many of their creators) have been lost, these powerful photos feel as immediate as a subway train thundering down the tracks.
