Spray Nation

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archives of one of the most renowned graffiti photographers of all time comes this remarkable collection of previously unpublished images of New York’s graffiti scene in the 1980s.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.

Hundreds of environmental and weather modifying technologies have been patented in the United States alone, and hundreds more are being developed in civilian, academic, military and quasi-military laboratories around the world at this moment. This book lays bare the grim facts of who is doing it and why.

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.
