Abstract:  
Abstract The aim of this study is to determine the shot peening media and parameters which can introduce the strongest residual stress profiles while keeping a limited surface roughness on carburized steels. Another objective is to evaluate the ceramic shots Zirshot HDC and compare them to traditional metallic media. The influence of initial roughness and hardness of samples before shot peening was also investigated. Keywords: shot peening, ceramic shot, DOE, roughness, residual stress
