Abstract

The work herein describes efforts made to determine the feasibility of ultimately utilizing a table top ultrasonic shot peening (USP) piece of equipment in a maintenance depot setting. To accomplish this, aluminum specimens were fabricated and subjected to conventional as well as ultrasonic shot peening, as well as laboratory tests, including; surface roughness and residual stress. Although the residual stress profiles of the USP samples were slightly different from those generated from conventionally peened samples, it was determined that each method yielded similar compressive stresses and depths of penetration. Even with these positive results, it was determined that the unit tested would probably not stand up to a depot environment, as it was not very robust.
