| Abstract: |
Cold gas dynamic spray technology, or cold spray, emerged as a practical technology in the 1980s from the Institute of Theoretical and Applied Mechanics of the Russian Academy of Sciences in Novosibirsk. Thirty years later, the commercial implementation of his technology is expanding at a fast pace. CenterLine is a world leader in design and manufacturing of industrial downstream injection cold spray equipment. In downstream injection, the spray powder is introduced downstream the nozzle throat, at the diverging low pressure side of the nozzle. This enables compactness, portability, and low cost. Todays downstream injection equipment can operate at conditions of pressure and temperature that enables the deposition of a wide range of materials for corrosion protection, restoration, repair, and additive manufacturing. This presentation describes the working principles of the equipment, latest developments, and already established commercial applications.
