Brain James, 28th Maintenance Group senior engineering and technical adviser, explains the cold spray process at Ellsworth Air Force Base, S.D., Jan. 25, 2016. Cold spray is a technology that accelerates small particles of the substrate [whatever the material is made out of] to achieve a mechanical bond upon impact restoring the part back to the original specs. Ellsworth Air Force Base personnel have been using this technology for more than two years, and the 28th Maintenance Group is expanding the capability by building a cold spray facility, which is slated to be fully operational in May.
