Spurred on by the initial success of cold spray applications, a wide range of industrial sectors have since shown a tremendous interest in the youngest of the thermal spray processes. The forerunner, oxide-free copper coatings, paved the way for a variety of materials to be successfully sprayed at the Linde Technology Centre in Munich. At the same time, the hardware for cold spraying also underwent rapid development. This now means that new materials can be processed with the highest efficiency and quality possible, using lower-cost nitrogen rather than helium which is decidedly more expensive.
