Deposition techniques
Cold spraying
In cold spraying, powders are sprayed with a supersonic compressed gas jet at temperatures below their melting point in very high velocity. The impact binds the particles into the surface and thick layers of deposited material can be built up rapidly. The deposition efficiency is very high, above 90% in some case.
Tipically applied are copper, aluminium, bronze and super alloys as well as steels.
