Experimental Study of Single Shot Process: Toward a Surface State Predictive Tool

Abstract

The present study aims at enhancing the comprehension of the interactions between shot and target during shot-peening process, with focus on the energy transmitted and roughness generation. A single impact approach was developed in order to establish relations between the process parameters, media and target properties, and the generated surface state. Al-6061-T6 plates were peened with only one shot made of different materials (ceramic, metals) under controlled process conditions (pressure, distance and angle). Process parameters such as incident and rebound velocities were determined by coupled fast-cam. This approach allows identifying key criteria combining media properties and shot peening process parameters, initial step, to monitor and optimize the surface topography of the peened sample.
