Woodhead Publishing The Cold Spray Materials Deposition Process: Fundamentals and Applications (Woodhead Publishing Series in Metals and Surface Engineering)

The cold spray process produces extremely dense, oxide-free coatings that make it ideal in such diverse applications as the control of corrosion and wear, metal repair and electronics. This important book reviews both the principles of the process and its practical uses. The first part of the book reviews its advantages and disdavantages compared to thermal spray coating. The second part discusses the role of such parameters as powders, nozzle design, particle temperature and velocity and particle-substrate interaction. The final part of the book analyses applications in such areas as improved wear and corrosion protection as well as repair of components and shielding from electromagnetic interference. Key Features: 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. Contents: Part 1 General issues: The development of the cold spray process; Comparing cold spray with thermal spray coating technologies; The advantages and disadvantages of the cold spray coating process; The economics of the cold spray process. Part 2 Cold spray process parameters: Cold spray process parameters: powders; The influence of nozzle design in the cold spray process; The role of particle temperature and velocity in cold spray coating formation; Particle/substrate interaction in the cold spray bonding process; Supersonic jet/substrate interaction in the cold spray bonding process; Portable, low pressure cold spray systems for industrial applications; Stationary cold spray systems for industrial applications. Part 3 Applications of cold spray coatings: Mechanical, thermal and electrical properties of cold sprayed coatings; Cold spray particle deposition for improved wear; The use of cold spray coating for corrosion protection; Electromagnetic interference shielding by cold spray particle deposition; Repair of magnesium components by cold spray techniques.
