| Abstract: |
Cold spray technology emerged as a practical technology in the 1980s from the Russian Academy of Sciences in Novosibirsk. Some of the good attributes of cold spray technology include the ability to deposit low porosity and oxide-free coatings with good adhesion and with no change to the microstructure of sprayed materials or substrate. Thirty five years later, the commercial implementation of this technology continues to grow in applications such as dimensional restoration in the aerospace industry. This paper describes the use of downstream injection cold spray, at low-pressures, to successfully repair damaged Alclad layers on aircraft skin, by obtaining dense coatings with sufficient adhesion to 2024-T3 aluminum substrates.
