Résumé :
This extensively updated and revised version builds on the success of the first edition featuring new discoveries in powder technology, spraying techniques, new coatings applications and testing techniques for coatings -- Many new spray techniques are considered that did not exist when the first edition was published!

The book begins with coverage of materials used, pre-spray treatment, and the techniques used. It then leads into the physics and chemistry of spraying and discusses coatings build-up. Characterization methods and the properties of the applied coatings are presented, and the book concludes with a lengthy chapters on thermal spray applications covers such areas as the aeronautics and space, automobiles, ceramics, chemicals, civil engineering, decorative coatings, electronics, energy generation and transport, iron and steel, medicine, mining and the nuclear industries.

Biographie:
Brad grew up in the countryside of Michigan on the outskirts of the small town of Tecumseh. Surrounded by corn and wheat fields, it was there he learned to harness his imagination. In sixth grade, he was selected for the Young Authors Program, which sparked his urge to write. Later, he graduated from Michigan State University, where he also studied martial arts and started writing his first novel. His home is now Chelsea, MI, where he lives with his wife, two daughters, and many rescued animals. Brad is the author of the epic science fiction adventure trilogy War of the Harbingers....
