The cold spray materials deposition process: Fundamentals and applications

V K Champagne, US Army Research Laboratory, USA

 - 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

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 2 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 will be a standard reference on this important process and its industrial applications.
